Crushing the uncrushable: Introducing the Trio® TC84XR cone crusher

Photo: The Trio® TC84XR cone crusher Pebbles contain valuable ore but without a crusher capable of processing them, pebbles can end up discarded or stockpiled. Weir Minerals has developed the Trio® TC84XR cone crusher – specifically engineered to perform in the most challenging applications, including pebble crushing. Pebble crushing is one of the toughest crushing applications on a mine site. Pebbles are rounded and very hard rocks that contain valuable ore. As ore is treated in a tumbling mill (SAG or AG), some rocks are hardened by the process and this hard, round-shaped material is known as pebbles. Without a crusher capable of processing them, pebbles often end up as lost product and are discarded or stockpiled. However, with the right technology, pebbles can be effectively crushed and the otherwise lost ore can be obtained. The Trio® TC84XR cone crusher has been specifically engineered to perform in the most challenging applications, including pebble crushing. Unlocking value, driving production The TC84XR cone crusher from Weir Minerals, quite literally, unlocks value – it transforms what would be a waste product into a saleable one. This is becoming increasingly consequential: as mines are getting deeper and ore is normally becoming harder and more difficult to extract, miners are consequently finding more pebbles. It’s often said that the first stage of mining is done by nature; rock that has been exposed to the elements has already undergone – and is undergoing – a process of erosion. In contrast, rock that’s been locked underground for millennia is harder and more difficult to crush and process. As well as adding significant value through increased production, the Trio® TC84XR crusher also helps prevent losses by reducing downtime. If pebbles are not properly processed and are, instead, allowed to build up in the mill, then they start to reduce processing capacity and can result in catastrophic plant and equipment damage. The Trio® TC84XR crusher’s (and the smaller TC series) unmatched ability when it comes to handling pebbles is one of the reasons why it’s widely regarded as one of the most reliable cone crushers on the market.  Tackling variable feed You only have to see the Trio® TC84XR machine alongside other cone crushers to appreciate just how robust it is. It’s 40-50% heavier than similarly sized machines and, as a result, it can process unstable feed and it just keeps on running. When it comes to crushing pebbles, weight really does matter. The ability of the Trio® TC84XR crusher to handle variable feed and crush pebbles is also partly a result of its large motor; it’s been designed with higher power capability than comparable cone crushers. Ultimately, this translates to a higher potential crushing force and therefore increase in production. Another feature that allows it to handle variable feed, as well as deal safely, is the fully-automated tramp-release and setting recovery system. Tramp material is metallic scrap that accidentally finds its way into the crusher; it has the potential to damage equipment and lead to stoppages. The tramp release hydraulics can also be used to safely clear the crushing chamber should a sudden disruption in plant power cause a shut-down of the cone crusher. The tight closed side setting (CSS) of the TRIO® TC84XR crusher is also crucial in enhancing its pebble crushing capabilities. The CSS defines the maximum product size and has a significant effect on crusher capacity and crusher liner wear. Trio® TC series cone crushers can be operated at a small CSS, 10 to 12 mm can be seen as a recommended operational setting for effective pebble crushing. Sometimes and in some applications, we can even go smaller, but this is dependent on the material characteristics and needs to be judged on a case-by-case basis. The TC84XR crusher also has very high clamp pressure, which holds the adjustment ring in place. Increasing the clamp pressure helps to control the adjustment ring position and deliver a CSS, eliminating bowl creep (i.e. where the bowl begins to move as crushing forces overcome clamping forces). Global support network The TRIO® TC84XR cone crusher can also be fitted with ESCO® wear parts, designed with superior ESCO® alloys, they can be custom designed based on your specific requirements. With over 100 years of casting expertise and in-house engineering and metallurgy, ESCO® transforms what was already a robust machine into one that, in the toughest conditions, is unsurpassed. With on-the-ground staff and service facilities already operating in more than 70 countries, Weir Minerals’ unmatched regional support network ensures product experts are always close to their customers.

QED celebrates safety milestone in Masbate

For the past six years of operations as a drilling contractor at the Masbate Gold Project (MGP), Quest Exploration Drilling (Philippines), Inc. has reached its goal of 1,000,152 safe manhours with 2,141 days without lost time injury (LTI) as of the day shift of November 12, 2021. The team has drilled over one million meters during this period. With an excellent commitment to safety and productive performance, QED started its RC in-pit grade control operations at the mine site in Aroroy, Masbate with a contract signed with MGP’s owner, Filminera Resources Corporation, in 2013. QED’s achievement is the result of obeying established safety management systems and guiding principles. In an interview with the Philippine Resources Journal, Wayne Smith, QED’s contract manager at the site, revealed detailed insights behind their safety performance. Smith explained that team in Masbate has been working together in the past nine years. “Our Masbate operations is basically run by a close team. We train and grow our employee’s knowledge on safety at work and at home to prevent incidents at all times. This process starts from Day 1 of their employment with QED,” Smith said. Describing QED’s Safety Culture At QED, everyone understands that a safe operation comes with hard work. Having the need to create a safe work culture requires effort from all team members. Through the commitment of the management, supervisors, and site safety personnel, coaching and mentoring became an integral part of daily routine for the Masbate team. “We have to refresh and remind employee’s all the time to continue with our safety culture to make sure we all go home safely each day from work. The same mindset applies with safety outside of work as well,” Smith explained. The pandemic has extended safety protocols to the households of each member of the Masbate team. Like in the past, the management has constantly reminded employees to practice what they learned from their training when they are at home, especially during occasions like Christmas breaks where people tend to lower their guard against unsafe practices. This part of the QED team’s “safety culture” has made dealing with COVID-19 easier. To prevent virus contamination, the movement of people from their homes to the workplace must be regulated. Getting used to safety discipline while at home contributed well to the adaptation process. Systems-based Approach Safety as a science is basically a system of establishing control measures. To implement such controls, the team uses a systems-based approach to manage training and to effectively run safety meetings and pre-task risk assessments. The system also includes communicating safe working procedures, inspections, and auditing processes. “Without these systems being in place, which gives a structure to the relationship between us (as the contractor) and the client, we would not have the control measures in place to prevent accidents from occurring,” Smith said. With over 50 people on board, QED’s Masbate team has been honed in the last nine years to face a long mine life. “Doing the things we have been taught to do” is a mantra for everyone in the QED management and workforce. Smith observed that a key element in their success is cultivating professional honesty among each team member. Training won’t work if some people still have the tendency to cover up mistakes, he said. “If you made a mistake and failed to report or concealed your actions, how would we fix it?” Smith often ask his team. Maintaining an open communication line between and among members of the team allows the reporting system to smoothly flow. On the positive side, initiatives that add value to everyday safety performance was not left out. Smith said motivations like giving commendations and rewards is also part of their organizational system.

Vulco® R67 mill lining rubber compound is revolutionising mine site mill operations

Photo: Inside the discharge end of a ball mill being fitted with spiral lifters and rubber grates. Vulco® R67 mill liners last significantly longer and deliver a measurable reduction in mill downtime, installation and maintenance costs. Vulco® rubber is renowned throughout the mining industry for its exceptional wear life and reliability in mill lining systems. These abrasion- and impact-resistant rubber compounds have been developed with advanced technologies by the Weir Minerals’ team of expert engineers and material scientists who are continually refining Vulco® rubber products to keep them at the forefront of mill lining systems technology. Having identified a need for higher-wearing rubbers for mill lining systems, the material science experts commenced developing an industry leading, premium-grade rubber compound with superior wear life and performance in mill lining applications. The result was the Vulco® R67 rubber – an optimum material which is manufactured with proprietary new compounds and innovative methods of processing to deliver outstanding wear life and longer uptime. Extensive field research, compound testing and site trials were conducted to ensure that it was not only able to withstand severe abrasion in typical mill system applications, but that it is best in class. In fact, it has been the most wear-resistant rubber compound that Weir Minerals has ever developed for mill lining applications. The R67 compound boasts a high hardness, elongation, tensile and tear strength, and is suitable for lifter bars, head/shell plates and grates. When it’s utilised in conjunction with metal cap mill liners, the result is a versatile, economical and efficient product that weighs up to 50% less than steel alone. The added benefit is a lighter product that’s faster, easier and safer to install. Revolutionising wear lining Since its launch in 2018, many mining operators from around the globe have implemented the R67 compound into their mill lining systems. They have reported as much as 20-40% improvement in wear life, which is resulting in fewer mill lining replacements and longer mill campaigns. This reduction in shutdowns has a dual benefit of increased cost savings and improved plant availability. What are the benefits for the mill operators? With a liner that can run significantly longer, operators have experienced a wide range of benefits including: Improved wear life A measurable reduction in mill downtime Increased uptime and processing Easier and safer installations Reduced maintenance costs In addition to this, the mines benefit from having an experienced and dedicated team from Weir Minerals who custom-engineer the liners to suit each mill’s unique requirements for optimal wear life. Global in-field success The R67 elastomer compound is changing the way mills operate - with exceptional results. Extensive global trials and commercial installations in the market have resulted in a number of successful outcomes across a variety of different grinding applications. From mines in the USA to Chile, the R67 has proven its outstanding performance consistently. As an example, a high-grade nickel and copper mining project in the USA had a problem where the liners in one ball mill were wearing out too quickly, leading to continued downtime and reduced processing. They were looking for a product significantly superior to the elastomer that they were using. Initially there was reluctance from the mine, as they had loyalty to their original mill supplier, however after Weir Minerals conducted a series of trajectory simulations and discreet modelling - to optimise the design and deliver the best process performance for the mill, they agreed to trial the R67 liners. At the end of the trial the R67 showed 30-40% better performance than the incumbent liners and the customer installed a full set of R67 liners in their mill.  Another trial in the USA took place in an iron ore mine with several dozen ball mills in operation. Here, Vulco® R67 liners delivered a 17% increase in life compared to the failed shell plates from the mine’s original mill lining system supplier. The company was extremely impressed with the results and installed a complete shell liner in their ball mill. Moving to Chile, a copper mine was keen to trial the R67 compound to see if they could improve the wear time of a competitor rubber liner. After a three-month trial, all liners were physically measured showing that the Vulco® R67 liners fully worn wear life projected from the actual wear would be 80% longer compared to the incumbent liners. Another copper processing plant in Chile trialled R67 composite liners in their SAG mill against two other compounds that are commonly used in the industry. After 12 months, there was a 48% and 62% wear life improvement on the other liners – proving that the R67 composite liners could withstand the highly abrasive environment. Helping customers optimise their process As leaders in material technology, Weir Minerals are continuously undertaking research and development to provide best-in-class products to mining customers, while helping them improve their bottom line. When using Vulco® R67 rubber compounds, our customers can feel assured they have a market-leading product that is backed by decades of experience, expertise, and proven effectiveness. This innovative rubber compound not only delivers superior physical and viscoelastic properties but is also a lighter and safer material to use. Where can you find Vulco® R67? Vulco R67® mill liners are made exclusively at Weir Minerals facilities in North and South America, Australia and South Africa, with plans to expand production into more regions in the future.

An Environmental Program that is Both Transformative and ‘Instagrammable’

Photo: A close-up on life after mining. Agata’s Bae Lawanen Garden features breath-taking and photogenic sunsets every day from its newly installed view deck that is shaped like a marine vessel. Agata continues to implement effective and sustainable rehabilitation programs that highlight its “Mining and Ecotourism” concept through the successful conversion of its mined-out areas into eco-tourism sites. Agata may not be the biggest nickel project in the country. But whatever it lacks in size is compensated through innovations, environmental programs, and socio-cultural projects replicated by other companies. Reforestation and rehabilitation Agata designed its rehabilitation programs to give equal importance to replanting mined-out areas and protecting existing forests to conserve its natural environment.  The balance between production and protection is essential in sustaining the community’s livelihood and protecting local resources. Since 2020, Agata has planted about 423,807 seedlings of forest and fruit-bearing trees as well as endemic plant species.  Since the time it commenced exploration, Agata’s reforestation activities have covered a total area of over 440 hectares.  The careful selection of trees and plants was curated by the company as a means to ensure the community’s livelihood at the end of Agata’s mine life. Nurseries were constructed to house and propagate endemic and bird-feeding tree species as part of the company’s Land Resource Management Program to increase the productivity of mined-out areas.  Its Ligaya Central Nursery has a capacity of 600,000 seedlings, while its satellite nursery has a capacity of 25,000 seedlings and is maintained by its partner community, the Lawigan Farmers and Fisher-folks Association (LAFFA). Agata also planted some 2,948 Giant Bamboo trees (Kawayan Kiling species) across seven hectares as part of its final rehabilitation and reforestation.  Agata Forester Jesnar Villareal said that bamboo absorbs more carbon dioxide than trees, generates a vast amount of oxygen, and can strongly root itself in the ground – which makes the soil more stable. Thematic landscapes Achieving a sustainable environment after mining is the focus of Agata’s vision for the future.  It was the first mining company to adapt thematic landscaping, which is a method of land use management where rehabilitation or revegetation is designed to beautify the area.    These “Instagrammable” landscapes also showcase the company’s best practices on solid waste management as the ornaments used are made from recycled materials.  One such photo hotspot is the Bae Lawanen Garden found within the admin camp, which has been frequented by visitors prior to the pandemic. Green innovations Agata produces its own organic soil fertilizers by using livestock wastes from the company’s own Mabakas Techno Demo Farm.  These organic fertilizers – mixed with kitchen food waste from the company’s mess hall – are recognized as a “soil builder” because of its property to improve soil quality.   Agata also trained local farmers on the production of the organic fertilizers for their own use.  In addition, the company implements a strong solid waste recycling program that has reprocessed 60% of all collected solid wastes this year alone.  It also created its own rain-fed irrigation system using plastic water bottles as rain catchment and storage, to keep a steady supply of water for its growing plants and trees. These environmental projects not only reduce the company’s carbon footprint but also help in its reduction of ecological waste. With the collective support across its ranks and host barangays, Agata cultivates a better and healthier environment for its communities; an enduring testament that – beyond a doubt – there is life after mining.

Portable XRF for Gold (Au) and Au Pathfinders for Mineral Exploration and Ore Body Vectoring

 Olympus’ X-ray fluorescence (XRF) analyzers provide high-performance, real-time geochemical data for rapid multielement characterization of soil, rocks, and ores. Recent advances in XRF technology have increased the number of elements measured, improved the limits of detection, and reduced analysis test times. Vanta™ XRF analyzers provide convenient and rapid measurement of many types of samples associated with Au exploration, within Au mines, Au mine labs, and refined Au products. Benefits Rapid indication of potential Au mineralization through XRF analysis of pathfinder elements in soil, drill cuttings, and drill cores Priority sample selection, maximization of analytical budgets, and improved drill target generation by prescreening samples with XRF Improved ore deposit understanding, modelling, and vectoring with less dilution and better Au recovery via XRF mapping of structural features and identification of mineralized and altered zones Inexpensive and rapid rock typing by using XRF for lithogeochemistry Associated Geochemical Signature of Au Deposits Source: Reflex Geochemistry Pathfinder and Alteration Geochemistry Most Au deposits have an associated geochemical signature (as shown in the table above). The XRF analyzer can detect these geochemical signatures, enabling geologists to better understand the geological system in which they are working. Typical Au pathfinder elements include As, Cu, Pb, Zn, Sb, Bi, Ag, and W. Typical XRF LODs for Common Au Pathfinder Elements with Vanta VMR GeoChem Model *120 s test time per beam, interference free SiO2 matrix; refer to Olympus LOD documents for further discussion on lower limits of detection (LODs) XRF Analyzer for the Detection of Gold It is common knowledge that handheld XRF analyzers do not support direct low level measurement of Au in geological samples (e.g., low ppm and ppb). The lab-based fire assay technique is commonly recognized as the method of choice for Au analysis. Au L-level X-ray lines are located in a very crowded area of the X-ray fluorescence energy spectrum. In this part of the spectrum, interference from other elements (e.g., As, Zn, W, and Se) can yield a false-positive Au determination. Direct measurement of Au by XRF can be achieved in specific cases such as high-grade (> 5 ppm) quartz vein environments (relatively interference free) or within refined Au products (where Au is present in very high concentrations). An increasing number of Au onsite mining laboratories are using XRF in place of, and as a supplement to, fire assays methods. Please refer to the Olympus Application Note “Use of Handheld XRF in Au Mine Laboratories.” Mines are also using Olympus handheld XRF analyzers for measuring Au in activated carbon.

THPAL commences Chromite Production

Taganito HPAL Nickel Corporation (THPAL), a mineral processing plant and a subsidiary of Sumitomo Metal Mining Co., Ltd (SMM), officially started its commercial operation of chromite last March 2021 to produce chromite concentrate. The company decided to commercially extract chromite to be used primarily as a raw material for stainless steel. With the Chromite Recovery Plant of the company, THPAL can now recover chromite simultaneously during the production process of nickel and cobalt mixed sulfides, the first intermediate product of the company. Chromite has brownish to black-colored mineral and is refined and processed into the intermediate product ferrochrome, widely used as a raw material for stainless steel and other special steels. This can also be used as paint pigment to produce Chrome Yellow for the textile industry, where large amounts of chromium compound as chemical to fix a dye are commonly used. According to Engr. Rey Prado, head of THPAL Chromite Recovery Plant, “It has been shown that there is an increase of the worldwide demand for chromite from November 2018 and the market is still growing. With this, the company’s target is to produce high quality chromite for quarterly shipment on demand of the customer.” By efficiently recovering not only nickel and cobalt but also its by-products such as scandium and chromite in THPAL, it will increase the cost competitiveness of its HPAL technology. This will likewise provide new materials for the stainless-steel industry, which is the backbone of the nickel business. By doing so, SMM’s presence in the global nickel industry through its subsidiary companies will push the realization of its vision of “Becoming the World Leader in the Non-Ferrous Metals Industry” by 2030. This will likewise add value to the low grade ores and increase the contribution of the company to employment generation and to the coffers of the government. Brief Description of THPAL Taganito HPAL Nickel Corporation (THPAL) is a mineral processing plant located at Taganito Special Economic Zone, Barangay Taganito, Claver in the province of Surigao del Norte, which employs the highly efficient High Pressure Acid Leaching (HPAL) technology to turn low-grade nickel ore into a manufactured intermediate product of high commercial value. With its estimated cost of 1.6 billion US Dollars, it became one of the largest foreign direct investment projects in the Philippines. THPAL’s plant is designed to have an annual production of 30,000 metric tons of Nickel and 2,640 metric tons of Cobalt in the form of Ni-Co Mixed Sulfide. This Ni-Co Mixed Sulfide will be exported to Nihama Nickel Refinery in Ehime Prefecture, Japan. THPAL is likewise the country’s sole producer of scandium – the rarest mineral on earth -- and on April 2021 THPAL started the commercial operation of its Chromite Recovery Plant to produce chromite concentrate.

AutoMine: Blazing the trails ahead

Photo credit: Sandvik Combining advanced sensing capabilities, sustainable battery-electric technology and artificial intelligence, the AutoMine Concept vehicle is Sandvik’s future vision for autonomous mining equipment. And it’s already operating in Sandvik’s test mine in Tampere, Finland. Jussi Puura, digitalization lead at Sandvik Mining and Rock Solutions, is excited about the AutoMine Concept vehicle, and no wonder. “This is essentially the way to the future and Sandvik’s roadmap to get there,” he says. “This shows what a typical piece of mining equipment could look like in 10 or 20 years. And more than that, it’s not just a vision in a slide deck presentation. It’s an existing, physical vehicle actually working down in our test mine.” His enthusiasm is understandable. In addition to being a cutting-edge battery-electric loader, the AutoMine Concept ve-hicle packs advanced surroundings perception in 3D, mapping technology and artificial intelligence to enable it to adapt and plan its own routes to find the most suitable paths, even in continuously changing environments. Ultimately, it repre-sents a big step towards comprehensively autonomous mining operations. This shows what a typical piece of mining equipment could look like in 10 or 20 years. It’s an existing, physical vehicle actually working down in our test mine. The AutoMine Concept vehicle is also a major milestone in Sandvik’s development of the AutoMine and OptiMine so-lutions. Since 2004, these digital systems have supported automated mining operations. The marketplace initially was hesitant to adopt such revolutionary solutions, but the last several years have seen a marked increase in demand. The cur-rent growth rate is strong, including in developing markets such as Africa, India, China and Latin America. The capabilities of the AutoMine systems have also seen a marked improvement over the years. However, more recently it has become increasingly clear that the next generation of mine automation is coming, and upgrades to the existing plat-form help unlock new, even greater capabilities. This developmental leap could be compared with recent developments in autonomous road vehicles, including innovations such as the Google car, Tesla and others. Also, developing markets and challenging mining conditions in particular require maximum reliability and robustness. Riku Pulli, president of the Rock Drills and Technologies division at Sandvik Mining and Rock Solutions, reveals more about the breakthrough technologies in the AutoMine Concept vehicle. “First of all, this vehicle is designed and engineered for automation from the outset,” he says. “The design philosophy of existing fleets is based on a conventional loader, which always includes a cabin, joysticks, pedals and so on.” The AutoMine Concept vehicle is designed exclusively for automated and remote operation. The AutoMine Concept vehicle is designed exclusively for automated and remote operation. There is no cabin at all, which means cost savings and the elimination of  unnecessary limitations, enabling more efficient and reliable overall design because there is no need for duplicated steering systems and controls, one for the human operator and one for the computer control system. Another major innovation is the tremendous expansion of sensing capabilities. Existing mining equipment is limited in this respect. It can essentially sense where the sidewalls of the tunnel are, for example, but not much more. The AutoMine Concept vehicle creates a true 3D view of its entire surroundings, including the vertical direction. “This opens up really significant possibilities compared with existing mine automation systems, which are restricted to gated areas separated from people and other equipment, much like security gates around robots used in manufacturing,” Pulli explains. The existing AutoMine safety system is based on isolation barriers that enable automated equipment to operate in des-ignated, barricaded areas, and stops equipment immediately if a safety barrier is tripped. The all-around sensing capability of the AutoMine Concept vehicle is designed to make isolation of automated operations unnecessary. The vehicle can stop or move around any obstacle on its route. “This is a huge improvement because it eliminates a host of limitations linked to mine automation,” Pulli says. “It has until now been necessary to separate automated mining operations from conventional manual operations. The new platform will increase operational flexibility tremendously because the isolation of automated operations becomes unnecessary. Work can go on around and among the automated vehicles simultaneously.” Why is it, then, that the concept vehicle is specifically a battery-electric loader? According to Pulli, Sandvik wanted to demonstrate that future mining equipment will be not only autonomous but also emission-free. Another reason is linked with the AutoMine platform. Most of the equipment controlled with this system consists of loaders, and what sets loaders apart from other mining equipment is their relatively high speeds, demanding performance requirements and round-the-clock operation at a high utilization rate in extremely cramped conditions. Sandvik wanted to set a benchmark: if the company was able to pull this off, it could be confident of its capability to transfer the technology to other types of mining equipment, such as drill rigs, where the requirements are typically less stringent. What will the next steps be? The capability to further scale the technology to other types of mining equipment is an early goal that should be met soon. Another focus area will be the technology mix, which now includes several types of scanner technologies and, for the first time in mining equipment, artificial intelligence. Some of these components will be imported to the existing AutoMine system in 2021. Automine concept vehicle: High-performance battery-electric loader   Surroundings perception thanks to 3D online mapping capabilities Adaptive capability to find the optimal route even in continuously changing mine environments   Instant obstacle detection and real-time reactions for collision avoidance Advantages: Safety: reliable collision detection and emergency stops   Flexibility: possibility to operate both conventional and autonomous vehicles in the same area   Productivity: unlimited potential for automated mining operations   Sustainability: battery-electric, emission-free vehicle

Seismic Velocity (P-S) Suspension Logging in Philippines

Photo credit: RDCL In-situ measures of seismic data is one of the key inputs in many infrastructure projects across Philippines. Understanding a project site’s seismic response is key to designing and engineering above ground structures, without it, you are guessing and often overengineering. There are many ways to gather seismic data, such as Vp and Vs (compressional and shear wave velocities). Surface techniques are commonly deployed as they require no drillholes. However, surface wave data can produce poor results if a site is “noisy” and are highly variable through different collection techniques and processing. A more direct measure of Vs and Vp is from in-ground, with drill holes. The most utilized method is downhole seismic, which generates a seismic source at surface and receivers are placed in the drill hole to record. This method should have grouted and PVC boreholes, and the holes need to be vertical. Extra drilling time means extra costs. A PS suspension logger allows for in-ground measures of Vs and Vp conducted from an open drillhole. This allows for rapid data collection immediately after a drillhole is completed. There is no requirement for grouted PVC holes. A PS logger can also work in marine environments allowing data from nearshore and offshore projects like wharfs and reclaimed land developments. A PS Logger is a robust, reliable, and repeatable seismic tool, which allows data from drillholes, without grouted PVC holes and has a high degree of accuracy producing better results for client’s engineering projects. Precision Data on Soil and Rock Physical Properties The PS Logger probe measures P (compression) and S (shear) wave velocities in a single borehole without the need for external energy sources, making it simple and quick to deploy and therefore cost effective, especially when compared to alternative methods. When combined with bulk density values (from a density log or from core sample tests) small strain moduli (Young’s, Shear and Bulk) can be calculated using simple formulae. How the PS Logger Works The PS Logger is a full waveform acoustic probe, designed to measure compressional and shear wave velocities in soils and rock formations. It operates using indirect excitation rather than mode conversion as in a conventional sonic. It can acquire high-resolution P and S wave data in borehole depths of up to 600m. It contains a unique design of powerful hammer source and two receivers, separated by acoustic damping tubes. To acquire data, the probe is stopped at the required depth and the source is fired under surface command. Firing causes a solenoid-operated shuttle aligned across the borehole axis to strike plates on opposite sides of the probe in turn, setting up a pressure doublet in the surrounding fluid. The resultant fluid motion produces a tube wave at the borehole wall with velocity close to the shear velocity of the formation together with a compressional wave. As the waves propagate parallel to the borehole axis, they set up corresponding fluid movements that are detected by the two-receiver combination (neutral-buoyancy 3D hydrophone for P waves and horizontally aligned geophone for S waves), allowing the wave velocities to be directly measured. The facility to stack multiple shots and filter the data as in normal seismic data acquisition is included in the operating software. Key Benefits The PS Logger works in a single fluid filled borehole, in contrast to cross-hole methods that usually require two or more specially prepared boreholes. The method works in open or grouted plastic cased boreholes and borehole muds generally do not need to be flushed prior to logging, without compromising borehole stability. The PS Logger is largely unaffected by path affects, which can be problematic for cross-hole methods. With an integral powerful source, energy delivery is constant throughout the extent of the borehole, independent of borehole depth, giving reliable velocity measurement in hard rock and the slowest of formations. The high vertical resolution (0.5m typical) allows for measurement of thin layers and is not affected by high velocity layers above low velocity layers. As no external source is required, this makes the system ideal for working offshore on barges, jack-up platforms, and drill ships. As the probe is suspended in the borehole, no clamping to the borehole wall is required, allowing faster acquisition. The PS logging can be conducted at the end of the drilling alongside any of the full range of conventional logging probes that Robertson Geo offers. The propagated waves are measured in the vertical plane providing the most useful information in anisotropic formations. When combined with bulk density values, the PS Logger provides a continuous strength profile, especially important when hard layers are encountered and CPT methods "refuse.” The relatively high frequency of the source, when compared to other methods, means that good data can usually be obtained in very noisy environments. On drill ships where engines, DP thrusters, generators and ancillary equipment contribute to the ambient noise, this is very important. The reversed polarity shear wave measurements provide unambiguous identification of shear wave arrivals. Drilling Matters Borehole conditions play a big part in data quality and that is where the drilling personnel should be involved. Rotary drilled boreholes always provide the best data (low rugosity). The PS Logger can produce good data in boreholes from 65mm to 400mm with the optimum range being from 75mm to 200mm. Inclined boreholes can also be logged providing the tilt is no more than 30⁰ from vertical. Where borehole stability is an issue, the logging is often split into separate runs whereby the drill string is retrieved in stages. To minimize possible loss of data, close liaison with the drillers, geologists and geotechnical personnel is required to confirm where the potentially unstable layers are (e.g. gravel beds). A shooting plan can then be made whereby the drill string can be withdrawn in stages to provide some open borehole while providing protection for the problematic zones. Due to the PS Logger’s tolerance to borehole muds, there is little or no preparation required on the borehole. Polymer or Bentonite-based muds can be extremely viscous with the limiting factor being the buoyancy of the probe. Where the use of thick mud fails to provide sufficient borehole stability the borehole can be plastic lined and grouted. Processing Full waveforms are recorded digitally at acquisition time across 6 channels (P wave, S wave left & S wave right at the near and far receivers) at a predetermined sample rate as low as 2.5μsec. The sample rate is carefully selected to be as small as possible to provide the best resolution but high enough to capture the arrivals within the listening window. Low pass filters can be applied at acquisition time and digital filters can be applied during or post acquisition. Using the acquisition software, the waveforms can be displayed, scaled, and filtered to allow for the picking of the first arrivals at each receiver. Automated picking is available but in most cases the arrivals are picked manually by experienced engineers. While the P wave arrivals are generally simple to pick, the S waves with their typically slow onset and possible superposition over the decaying P waves benefit from an experienced eye to avoid "cycle skipping.” From the receiver separation (1 meter) and the arrival times the velocities are automatically calculated. Once the arrival times and velocities have been determined, the data is opened in a second program (also supplied with all PS logger systems) that creates and manipulates logs of the data. If a bulk density profile by depth is available, it can be combined with velocities to give the small strain moduli, Young’s, Shear and Bulk and Poisson’s ratio. Finally, all data can be outputted in industry standard LAS format. From unconsolidated soils to the hardest of rocks, the PS logger gives proven results Simplicity of deployment combined with a minimum of borehole preparation and the ability to obtain high quality velocity data in unconsolidated formations and hard rocks make the PS Logger a sound economic choice for Geotechnical and Civil Engineers investigating rock strength.

QES Technology Philippines, Inc. Continuously Provides Complete Solutions to Successfully Sustain Mining Industry

​ Photo: SciAps XRF X-200 for mining site exploration (Philippines) and SciAps LIBS used by NASA for Mars exploration The year 2021 has been the transition from the pandemic-stricken year 2020 towards economic recovery and full adaptation on the ‘new normal’, as the mining industry successfully sustained and continues to move forward with the country’s mineral riches. [1] In line with this, QES Technology Philippines Inc. offered its technical support to private mining sectors and government bodies, for assistance on X-ray Fluorescence (XRF) analyzers. QES catered both sales and services of handheld and benchtop ED-XRF. On August 2021, QES completed their newly renovated Demo Room which houses demo units for benchtop ED XRF (SPECTRO CUBE), Arc Spark OES (SPECTRO MaxX), handheld XRF (SciAps X300 and X200), handheld LIBS (SciAps Z200C+) and other equipment/instrumentations. These are available for demo from Monday-Friday office hours at their head office in Page 1 Bldg., Acacia Ave., Madrigal Business Park, Muntinlupa City, still in compliance with standard health protocols. QES Technology Philippines, Inc. Demo Room at Page 1 Bldg., Acacia Ave., Madrigal Business Park, Muntinlupa City In partnership with Southgreen, QES assisted Mines and Geosciences Bureau (MGB) in pioneering the first regional installations of handheld XRF analyzer for Region VI and Region IX. A 3-day SciAps XRF X-200 virtual product training was conducted for the first time and ended successfully in coordination with MGB Central Office. The SciAps handheld LIBS Z-200 C+ was also purchased by a private sector used for Research and Development also catering the C requirement in alloy and geological samples. This is also the equipment used by NASA for the Mars exploration project. The use of “XRF guns” as termed by geologists, have dramatically improved the method of exploration so this is now a must-have tool for site projects exploration and face sample evaluation. This year’s milestone, also a solid indication that the Philippine Mining Sector is thriving, is QES’s record breaking sales of fifteen (15) and still counting units of benchtop ED-XRF analyzer Spectro XEPOS. QES has established and continuously dominates the sales, service, and calibration of ED-XRF analyzers in the Mining Industry from Isabela to Tawi-Tawi, through the Spectro XEPOS which has always benchmarked the ED-XRF analyzers in the mining industry known for its simple, accurate, and efficient analysis. One of the major strengths of QTP is the availability of regional technical support. Two engineers are based in Cebu, one in Clark, three in Manila and one in Surigao to fulfill the response time promised to customers. Along with that is the digitalization of equipment maintenance and repair tracking, QR code sticker is now a standard to new equipment installations and being rolled out to existing ones. The end-users can now conveniently scan the QR code using their phone or tablet and it will present the maintenance history of the equipment. The end user can also take photo of the QR code send it to their purchasing department so they can verify the parts are already installed to close the related transaction with ease. To assure continuous growth and learning, QES joins the 2021 ANMSEC and organizes webinars on Nickel Ore Mining particularly on exploration, sample preparation, calibration (for end users), and complete mining solution.
