The Philippine mining industry, while rich with potential, faces ongoing challenges in operational safety and efficiency. With the landscape of mining continuously evolving through technological innovation, there is a significant shift towards enhancing not only productivity but also environmental stewardship and worker safety. This article explores the proactive steps mining companies can take, with the support of companies like Fluke, to enhance safety and reduce operational downtime while reducing their impact on the environment.

Embracing evolving technologies

A prominent trend in the mining industry in recent years is the electrification of assets. The gradual shift from diesel to electric vehicles within mining operations is an example. This transition not only promises to reduce greenhouse gas emissions but also enhances operational efficiency. While new technologies are more easily embraced in new mine set-ups, the implementation in remote and old mines is hampered by the substantial investment and logistical considerations required for the introduction of new infrastructure to support electrification. Automation, powered by artificial intelligence tools, further complements this shift, enabling more precise control over mining operations and increasing safety by reducing human exposure to dangerous conditions.

Evolving the workforce

As technologies evolve, so too must the mining workforce. Upskilling is essential not only for operating new electric and automated equipment but also for prolonging the lifespan of machines, avoiding unplanned downtime and maintaining safety standards. Training programs are vital to ensure that workers are proficient in the use of the latest technologies to manage safety during mining operations.

Ensuring that all personnel are well-trained and aware of safety protocols is non-negotiable. The use of tools and machinery with the correct safety ratings, particularly in environments with electrical hazards, is crucial. Furthermore, continuous training and a strong safety culture within the organization play important roles in preventing accidents and ensuring operational efficiency.

In addition to providing professional electronic test tools and software for measuring and condition monitoring for the mining industry, Fluke supports their use with comprehensive, customized training. This ensures that all involved personnel know how to use the tools and operate them safely. While mining companies provide the necessary tools and training, the onus is equally on individual operators to understand and implement safety standards. Knowledge and vigilance are key defenses against potential dangers in the field.

Adopting proactive maintenance procedures

Equally important is the implementation of best practices to maintain operational efficiency and reduce downtime. Predictive Maintenance stands out as a forward-thinking approach to manage this goal. Predictive maintenance supports the identification of potential problems before they cause operational disruptions and allows for timely interventions that can prevent costly downtime. For example, a mining dump truck tyre cost can range 5k to 20kUSD. Early signs of air leaks from the mining dump truck tyre or pneumatic system can be spotted with the acoustic imaging solution Fluke-ii910 to prevent the costly breakdown. This process involves screening for abnormalities, diagnosing the root cause to avoid repeated failures, and undertaking the necessary repairs in the field to ensure continuous operation and safety. Fluke supports its mining clients with a range of condition-based measurement solutions to help identify invisible conditions that can compromise safety in the mine such as air leaks, mechanical bearing misalignments, power interruptions and electrical partial discharges.

Establishing a routine preventive maintenance schedule helps reduce unplanned downtime, which is often more costly and hazardous than planned time-outs. Scheduled maintenance is not just a cost-saving measure, it is a critical safety practice. Adopting a maintenance schedule can not only significantly extend the lifespan of fixed operational assets but can prevent the severe wear and tear that leads to unexpected failures, safeguarding both the machinery and the miners.

Fluke also adds value by consulting on ways to prolong machine life with the quality of the energy source powering equipment through its Power Quality Analyzer solutions. The cleaner the electricity powering the equipment, the lesser stress is placed on the machine, maximizing its lifespan. Use the unique energy loss calculator in the power quality analyzer Fluke-1777 to help you identify your energy wastes. The benefits to the environment are a natural by-product.

With New Practices Comes Great Responsibility

No business today is exempt from incorporating sustainable practices into their operations, including those in the mining industry. New technologies facilitate eco-friendly operations, significantly reducing the environmental impact of an industry that has traditionally been reliant on fossil fuels. For instance, adopting renewable energy sources and optimizing resources use are critical steps towards sustainable mining.

*Fluke Solar solution ensures electrical safety in Solar*

NICKEL ASIA CORPORATION ANNOUNCES P1.12 BILLION NET INCOME FOR THE FIRST HALF OF 2024

Listed natural resources development company Nickel Asia Corporation announced its unaudited financial and operating results for the six-month period ended June 30, 2024, with an attributable net income (net of minority interest) of P1.12 billion, lower than the P1.75 billion reported during the same period last year.

Earnings before interest, taxes, depreciation, and amortization (EBITDA) amounted to P2.96 billion against P4.79 billion in the prior year

Revenues from ore sales declined by 16 percent year-on-year to P7.79 billion from P9.29 billion due to lower ore prices resulting from the nickel oversupply. Meanwhile, the Company’s operating mines sold a combined 8.16 million wet metric tons (WMT) of nickel ore during the period, higher by 8.5% than last year’s 7.52 million WMT.

The weighted average nickel ore sales price during the period decreased by 26 percent to $16.60 per WMT against $22.32 per WMT in the same period last year. The company realized P57.50 per US dollar from these nickel ore sales, a 4-percent increase from P55.33 last year.

Breaking down the ore sales, the Company exported 4.23 million WMT of saprolite and limonite ore at an average price of $21.95 per WMT during the period from 3.66 million WMT at $28.22 per WMT in the same period last year.

Likewise, the Company delivered 3.93 million WMT of limonite ore to the Coral Bay and Taganito high-pressure acid leach (HPAL) plants, the prices of which are linked to the London Metal Exchange (LME) and realized an average price of $7.94 per pound of payable nickel, equivalent to $10.84 per WMT. This compares to 3.86 million WMT at $11.03 per pound equivalent to $16.72 per WMT last year.

NAC also recognized losses from its combined equity share in investments in the two HPAL plants in the amount of P388.20 million against P77.07 million losses in the prior year.

Renewable Energy

For the first half of 2024, Emerging Power, Inc.’s (EPI) subsidiary Jobin SQM, Inc. (JSI) increased generation by 54 percent to 117,935 megawatt hours due to a significant increase in overall capacity. Last Feb. 28, 2024, JSI successfully opened an additional 72- MWp in Sta. Rita, Subic, expanding capacity to 172-MWp.

Higher revenues and effective cost management kept the EBITDA margin at 85 percent and resulted in a 58-percent increase in EBITDA to P524.3 million.

EPI expansion continues

The construction of the 145-MWp Subic-Cawag solar project is expected to begin by the fourth quarter of this year, while commercial operations are scheduled to start by the fourth quarter of 2025.

Likewise, Greenlight Renewables Holdings, Inc., EPI’s joint venture with Shell Overseas Investments B.V., is constructing its solar project in Leyte, with an initial 120-MWp slated to be completed by the first quarter of 2025.

Pre-development activities for a 45-MWp solar project in Botolan, Zambales is also ongoing.

“Our three new nickel projects, namely Dinapigue, Bulanjao, and Manicani will supplement our annual nickel ore production volumes to help supply the ever-growing demand for nickel ore driven by both the stainless-steel and EV markets. Furthermore, our diversification into renewable energy continues with three more projects in the immediate pipeline, which brings us closer to our 1-GW goal by 2028,” said NAC President and CEO Martin Antonio G. Zamora.

Tacloban airport terminal phase 3 construction to start soon

The Department of Public Works and Highways (DPWH) is preparing to implement the PHP1.5 billion third phase of the Daniel Z. Romualdez Airport's passenger terminal building construction here.

The third phase covers the provision of public toilets, ticketing booths, waiting areas and waiting sheds.

Other components are rescue and firefighting facilities, guardhouses, motor pool and maintenance buildings, pump rooms, fuel stations, and material recovery facilities.

The DPWH will bid out the project within the month and start construction later this year or early next year.

DPWH Eastern Visayas Director Edgar Tabacon said they are finalizing the detailed engineering design while waiting for the completion of the first and second phases.

“Building an airport terminal building is not our regular activity. This is challenging and that is why we asked for assistance from the Department of Transportation and contractors for the first two phases,” Tabacon said in an interview on Friday.

The construction of the terminal building is already 79 percent complete as of May, the supposed target completion month.

The ongoing works for the PHP761-million project focus on the main bridge, electrical and mechanical aspects, fire protection, and masonry.

The Regional Development Council said that although the project experienced delays, the Civil Aviation Authority of the Philippine project management office closely monitors the catch-up plan of the contractor.

The second phase of the new passenger terminal building, with a PHP1.05 billion budget, started on Jan. 26 and is up for completion early 2026. Ongoing works include roofing and architectural works.

The airport was the seventh busiest in 2022 with 1,489,803 inbound and outbound passengers.

Marcos attributes economic growth to infra investments, construction

President Ferdinand R. Marcos Jr. on Friday vowed that his administration would continue pursuing job-generating initiatives that could help in further transforming the Philippine economy.

Marcos made the pledge, as he attributed the 6.3-percent economic growth in the second quarter of 2024 to the increase in investments and construction under the Build Better More program.

“Inuulit ko, balewala lahat ng ating ginagawa kung walang pagbabago sa buhay ng mga Pilipino (I repeat, everything we do is meaningless if there are no changes in the lives of Filipinos),” he said in a video message uploaded on the Presidential Communications Office’s official Facebook page.

“So I assure you, this government will continue to invest in job-generating infrastructure, social protection programs, health and education for all Filipinos. We will not rest on our laurels but use them to propel us forward into social and economic transformation,” he added.

The country’s economic growth accelerated to 6.3 percent in the second quarter of 2024, higher than the 4.3 percent during the same period last year and the 5.8 percent in the first quarter of this year.

He said the government is doing everything to give Filipinos “decent and formal” jobs to elevate them to middle class.

“Kaya patuloy ang ating pagbibigay ng sapat at kalidad na trabaho (That’s why we continue to provide adequate and quality jobs). This June, the unemployment rate dropped to 3.1 percent, one of the lowest on record for the last two decades. Over 50.3 million Filipinos are now employed, with 63.8 percent of them in the formal sector,” Marcos said.

Marcos assured Filipinos of his administration’s commitment to combat poverty, saying the goal is already “within its reach” as the latest poverty rate also dropped to 15.5 percent.

“[That] means we have lifted two and a half million Filipinos out of poverty and only 10.9 percent of Filipino families remain poor. Our goal is to further reduce this rate to 9 percent by 2028, and improve the lives of eight million Filipinos,” Marcos said.

A Technical Overview of a Water Access Tunnel Construction built by Filipino Mining Engineers

Part 1

A group of an all-Filipino Mining Engineers worked under the auspices of Paramina Earth Technologies, Inc. (PARAMINA) for a civil construction tunnel project. These Mining Engineers developed and excavated an 8m wide x 7m high x 1,011m long tunnel safely, without a single lost time accident (LTA) accident and or rockfall incident as a Subcontractor and without the help of a Civil Engineer. The project applied the NATM following international tunnel design, plans and standards. Completion of the tunnel project was remarkably ahead of the adjusted timeline including the remediation works.

The project is the Upper Wawa Pumping Station Water Access Tunnel owned by WawaJVCo, a joint venture company of Prime Infrastructure Capital, Inc. an Enrique Razon corporation and the San Lorenzo Builders and Developers Group, the grantee of the water rights of the project. The joint venture company is developing the Wawa Bulk Water Supply Project, “an infrastructure project of the Philippine Government and will address the growing concern of water scarcity and is expected to minimize the risk of flooding in the capital region and in the nearby province of Rizal. It will be the biggest water source built since 1967 and will supply at least 518 million liters per day through Manila Water Company. CTTO ” The main beneficiary of the bulk water supply project will be the eastern communities of Metro Manila and Rizal.

The water access tunnel project is part of the second of two water supply infrastructures of WawaJVCo. The tunnel designed by Lombardi SA was constructed to ensure that it will last for a minimum period of 100-years, therefore, the group of all-Filipino Mining Engineers who built the tunnel had to pass through very stringent QA/QC requirements which had to be followed and implemented to the minute detail.

The all-Filipino Mining Engineers who developed and excavated the tunnel were Mining Engineers who used to occupy and manage senior positions in various mining and tunneling projects in the Philippines and overseas; supported by a group of experienced junior Mining Engineers who supervised the shift operations. At least fifty Filipino multi-skilled tunnel equipment operators were at the forefront of the tunnel excavation operations.

Another group of at least forty Mechanical and Electrical Engineers and technicians formed the equipment maintenance and support group.

Two twin boom and one single boom electro-hydraulic jumbo drill rigs were the main drilling equipment. Two side dump loaders, three 20-tonne underground trucks and three dump trucks were used for mucking, loading and hauling. Blasting was designed using a computerized shot-plan and varied according to the rock and ground condition. Two robotic shotcrete machines and two high-and-low-pressure grouting machines were used for mechanized shotcreting and grouting respectively.

The tunnel support design was the greatest challenge of the project because there was limited geotechnical information provided. Every advance or blast was closely monitored as the crown and side supports and the blasthole drilling depths depended on the rock structure which was defined by the RMR of the active face.

Water is life. The Filipino Mining Engineers who built the tunnel are proud to be part of the commitment of WawaJVCo, the owners of the project to provide a new source of potable water, sustainable in the next 100 years.

Purpose and Magnitude of the Project

The “Upper Wawa Pumping Station,” is one crucial component of a Mega-Infrastructure Project better known as the “Wawa Bulk Water Supply Project,” is considered the largest potable water source to be constructed in the country since 1967. It comprises of four (4) major integral components or sub-projects of the Mega Infrastructure, namely, the Upper Wawa Dam and Spillway, Reservoir, Pumping Station and Transmission or Water Conveyance Pipeline. The Water Access Tunnel forms part of the Transmission or Water Conveyance Pipeline component of the Mega-Project.

The primary objective of the Wawa Bulk Water Supply Project is to address the perennial water scarcity issue in Metro Manila. This challenge has been exacerbated by population growth driven by migration, rapid urbanization, and economic opportunities. Once completed, this ambitious undertaking will establish a reliable source of potable water supply for Eastern Metro Manila, specifically serving the so-called East Zone Concession managed by Manila Water Co.

The Upper Wawa Pumping Station plays a pivotal role in achieving this goal. It is designed to supply a minimum of 518 million liters of water daily (MLD), with an additional standby capacity of 259 MLD, resulting in a total pumping capacity of 777 MLD. The Tayabasan River, situated in Barangay Calawis, Sitio Apia, Antipolo, within the Upper Marikina Watershed, serves as the primary raw water source. This river is further supported by several smaller tributaries spread across the Marikina watershed. Through this comprehensive project, the region will gain access to a sustainable and essential water supply, quenching the thirst of East Metro Manila’s residents in the next 100-years.

Scope of Tunnel Project and Technical Description

The scope of work for the Main Access Tunnel, a critical component of the Water Conveyance Pipeline within the larger mega-project, mandates that the tunnel Subcontractor undertake the excavation work by drilling and blasting, as well as the transportation and disposal of the muck through synchronized activities utilizing specialized equipment such as Furukawa, hydraulic twin boom jumbo drill rigs with man basket, Dali, 20-tonne low profile trucks, SDLG, side dump, 3cu.m. loaders and XCMG, robotic shotcrete machine among the capital equipment used in the project.

As the excavation advanced, the project required the installation of galvanized self-drilling anchor and all threaded rock bolts which were grouted to stabilize the newly exposed tunnel surfaces so that drilling and blasting can immediately commence after the newly excavated ground was fully shotcreted. A vast part of the process entailed the application of 50mm shotcrete immediately after scaling using a Komatsu excavator equipped with a hydraulic breaker, then 100mm thick shotcrete applied thereafter and before the start of drilling. The shotcrete mix is a special concrete mixed with additives and synthetic and or steel fibers and applied using the XCMG mechanized robotic shotcrete machine.

To ensure that ground water is drained and will not accumulate at the crown and sides of the tunnel, drilling of drainage and or weep holes using the MTI Single boom hydraulic jumbo drill was essential. Each weep hole is inserted with perforated drainpipes wrapped with non-woven geotextile.

Additionally, it was also necessary to execute variation works on an as-needed basis. The provision of essential support services is also part of the Bill of Quantities (BOQ), including the supply of adequate ventilation, water, power, and compressed air.

Temporary field offices, equipment maintenance workshop and personnel accommodations, ensuring a comprehensive and supportive environment for the project’s successful completion was also constructed.

Technical Requirements

The tunnel which was required to be driven was 8m wide and 7m high, extending over a total length of 1,011 meters. The specific dimensions for excavation and reinforcement are determined based on the rock mass rating (RMR) for each tunnel segment, as assessed and evaluated by Geologists and Geotechnical Engineers. Depending on the RMR of the tunnel’s face which is evaluated every after blasting, the tunnel designer and the Geotechnical and Geological Engineers considered six distinct support types. The support type spectrum ranged from Support Type P (for Portal), Support Type 5, down to Support Type 1, each tailored to reinforce the crown and sides of the tunnel as the excavation progresses, resisting the impact of drilling and blasting and to maintain the structural integrity of the tunnel to be able to last for 100years.

Support Type P is required to support the tunnel Portal which had Rock Mass Rating (RMR) between 0 and 20 and was intended for the excavation of the East and West portals of the Main Access Tunnel. The dimensions of Support Type P are 8.38meters wide by 6.74meters high allowing for the installation of Steel Rib Supports (SRS). This support system integrates the installation of Steel Rib Support (SRS) made from 200mm x 200mm H-beams using a specially designed “hook” attached to an excavator; a protective “umbrella” of grouted galvanized Self Drilling Anchor (SDA) rock bolts; a Shotcrete lining, 400mm thick enough to cover the whole SRS. Additionally, the structure is equipped with weep holes, into which eight 50mm diameter perforated drainage pipes wrapped in non-woven geotextiles are installed. As it was difficult to apply shotcrete at the back of the SRS, the sides of the SRS were drilled with holes in regular distances and were in-fill grouted using high-pressure automatic cement grout machines.

Conversely, Support Type 1 was designed for tunnel sections 7.78m wide by 6.44m high, intended for RMR ranging from 81-100. The support in these areas consists of sporadically placed grouted Dywidag split-set type rock bolts, 46mm diameter and 4 meters long, along with 8-pieces of 50mm diameter perforated drainpipes wrapped with non-woven geotextile. Due to the inherently stable nature of the rock mass, no shotcrete lining is applied in these sections.

Support Type 2 was designed for RMR 61-80 with tunnel dimensions 7.88m wide x 6.49m high. The support consists of 11pcs fully grouted Dywidag hollow all-threaded galvanized rock bolts, 25mm diameter x 4 meters long. Shotcrete thickness was 150mm including the initial 50mm after scaling, after which 50mm drainage holes were drilled and inserted with 50mm diameter perforated drainpipes wrapped in non-woven geotextiles.

Support Type 3 had similar excavation dimension as Support Type 2 but is designed for RMR equivalent to 41-60. The main difference is that the number of rock bolts is 15pcs fully grouted Dywidag hollow all-threaded galvanized rock bolts, 25mm diameter x 4 meters long. The number of drainpipes is the same as Support Type 2, but the shotcrete thickness is 300mm.

Support Type 4 required an excavation dimension of 8.28m wide by 6.69m high, designed for RMR equivalent to 21-40. This category when encountered was supported by a combination of the installation of 200mm x 200mm SRS, grouted galvanized SDA rock bolts, R38 x 4 meters long complete with plates and nuts, 350mm thick shotcrete covering the entire SRS and installed with 50mm diameter x 2m long perforated drainpipes wrapped in non-woven geotextile.

Finally Support Type 5 required an excavation dimension of 8.38 m wide x 6.74 m high for RMR ranging from 0-20. This support type consisted of a combination of the installation of 200mm x 200mm SRS, SDA galvanized rock bolts, R38 x 4m, 400mm thick shotcrete enough to cover the SRS and 8-pieces x 50mm perforated drainpipes wrapped with non-woven geotextile.

The various designs of Support Types ensure the stability and integrity of the tunnel, adapting to the varying rock conditions which were encountered during the actual excavation and were designed for the tunnel to last for 100years.

SMPC reports 41% decline in Q2 earnings to P6.0B; H1 net income falls 34% to P12.6B

Integrated energy company Semirara Mining and Power Corporation (SMPC) posted a 41-percent drop in second-quarter earnings to slightly over P6.0 billion from P10.2 billion the previous year, as coal and electricity prices continued to subside from historic levels.

“Despite our efforts to manage costs and improve operational efficiencies, the persistent decline in global coal and electricity prices has significantly impacted our financial performance,” said SMPC president and COO Maria Cristina C. Gotianun.

From April to June, average Newcastle Index (NEWC) and Indonesian Coal Index 4 (ICI4) both declined by 16 percent. Average NEWC fell from US$160.7 to US$135.6, while ICI4 dropped from US$65.1 to US$55.0.

Overall average selling price (ASP) of electricity decreased by 10 percent, from P6.22/kWh to P5.58/kWh, due to lower spot market prices and fuel costs for baseload plants.

Quarter-over-quarter (Q1 2024 vs Q2 2024), SMPC net income contracted by 8 percent from P6.5 billion owing to lower coal and electricity sales volume and average selling prices.

From January to June, the company’s earnings dropped by 34 percent from P19.2 billion to P12.6 billion due to the combined effect of weaker selling prices, higher total coal production costs and increased coal and electricity sales volume.

“The second half of the year should be more of the same for us in terms of coal prices. We also expect coal production, electricity demand and spot prices to taper because of the rainy season,” Gotianun added.

Coal Operating Results

For the second quarter alone, total shipments rose by 2 percent from 4.5 million metric tons (MMT) to 4.6 MMT on stronger domestic demand.

Domestic shipments accelerated by 16 percent, from 1.9 MMT to 2.2 MMT, primarily driven by higher sales to subsidiaries SEM-Calaca Power Corporation (SCPC) and Southwest Luzon Power Generation Corporation (SLPGC).

During the same period, Semirara coal ASP slumped by 33 percent, from P4,151 per metric ton (MT) to P2,780 per MT. This decrease was due to stabilizing coal indices and an increased demand for non-commercial grade coal, which is sold at a lower price.

Total production surged by 73 percent, from 3.0 MMT to 5.2 MMT, primarily due to lower rainfall levels and the near depletion of Molave mine last year, which created a low base effect.

Power Operating Results

Overall plant availability slightly improved from 80% to 81%, as fewer outage days of SLPGC offset the 77-day planned maintenance outage of SCPC Unit 2.

Total average capacity during running days increased by 17 percent, from 685 MW to 801 MW, due to the restoration of SCPC Unit 2’s dependable capacity to 300 MW on May 27, along with reduced deration in SLPGC plants.

Total gross generation improved by 12 percent, from 1,212 GWh to 1,352 GWh, driven by higher SLPGC plant availability and average capacity, along with the restored capacity of SCPC Unit 2.

Higher gross generation led to a 12-percent increase in total power sales, rising from 1,097 GWh to 1,228 GWh. Majority (59%) of the generated electricity was sold to the spot market, with the remainder sold through bilateral contract quantities (BCQ).

Spot market ASP fell by 12 percent from P7.11/kWh to P6.25/kWh, while BCQ ASP increased by 2 percent, from P4.52/kWh to P4.62/kWh.

At the end of the second quarter, only 33 percent of the 840MW dependable capacity of SCPC and SLPGC are contracted. Net of station service, which varies from time to time, SMPC has 481.6MW available for sale to the spot market.

President Marcos Jr.’s 2024 SONA Highlights on Infrastructure, Energy, and More

July 24, 2024

President Ferdinand Marcos Jr. received resounding rounds of applause several times during his third State of the Nation Address 2024 (SONA), particularly on the final part of his speech when he announced the ban on Philippine Offshore Gaming Operators (POGO).

The SONA 2024 was held on Monday, July 22, 2024, at the Batasang Pambansa Complex in Quezon City.

Among other things, his State of the Nation Address covered various significant national issues from education, agriculture, defense, cybersecurity, tourism, and more.

“As we enter the mid-term, our infrastructure development remains sustained, strategic, and on schedule,” the President said.

“Aside from agriculture and disaster risk, our other vital sectors and pillars — such as education, health, energy, low-cost housing, transport, information technology — they all stand to benefit from our aggressive infrastructure development, as befitting our upper middle-income economic target.”

He mentioned that despite the challenges during the past two years into this Administration, there has been a steady progress towards the targets in the medium-term.

“Our power and internet services are continuously being upgraded in both capacity and connectivity.”

Unified Philippine Grid

The President mentioned that the energy sector looks bright and promising with completion of projects and new investments. With that, he expected that the nation’s power supply will increase steadily to meet the growing demands in the future.

He also mentioned that government is urgently addressing power shortages and the systemic causes of blackouts in unserved and underserved areas.

Through microgrids, off-grid systems, and missionary small power utilities that supports solar power, the President said these will provide solutions to places that need a steady supply of electricity.

“Running through Bataan, Pampanga, and Bulacan, the newly inaugurated Mariveles-Hermosa-San Jose transmission line will further strengthen the reliability of the Luzon power grid.”

He announced that in the Visayas, all stages of the Cebu-Negros-Panay backbone project have been completed.

“This project shall serve to stabilize the power situation in Western and Central Visayas, and avert recurrences of power outages experienced in the past,” he noted.

He said that because of these projects, blackouts at Panay Island were prevented from April until June despite the yellow and red alerts in the region.

The President noted that the Dumanjug-Corella Line of the Cebu-Bohol Interconnection Project was energized, enabling the transfer of power between Cebu and Bohol.

“With these systems currently operating at capacity, these major power lines shall contribute to the efficient power exchanges not only between Luzon and the Visayas, but also involving Mindanao. Energy sharing and transfers between, among, and within the three island groups have now been made possible with the energization last January of the Mindanao-Visayas Interconnection.”

“The energization of the Mindanao-Visayas Interconnection is a defining moment not only for the power sector but for the entire country. Finally, we have connected the power grids of all three major island groups.”

“The ‘unified Philippine Grid’ is a fulfillment of the dream, whose seeds were planted in the 80s, through a vision bolstered by R&D, which we accomplished by applying typical Filipino persistence and dedication,” he stated.

Addressing the high cost of electricity, President Marcos Jr. gave assurance that government will continue to add power infrastructure that will contribute to the lowering the electricity rates and providing fair charges to consumers.

Roads and Railway Renaissance

President Marcos Jr. reported that as of May of this year, 12,000 kilometers worth of roads and more than 1,200 bridges have been completed and upgraded across the country.

“Of note, we have provided the budget to upgrade 367 bridges and almost 1,600 kilometers of road along our country’s longest thoroughfare — the Maharlika Highway — from Luzon all the way to Mindanao.”

“Moreover, significant segments of major expressways, which are part of the Luzon Spine Expressway Network, have now been opened to the public.”

By the end of this year, he announced that the C-LEX, NLEX-SLEX Connector, and the Plaridel Bypass will be fully completed, while the CALAX and the C5 South Link will be fully operational by next year.

“Under our Inter-Island Linkage Bridge Program, we expect two major bridges to be opened to motorists this year. One is the Panguil Bay Bridge — touted as the longest water-spanning bridge in Northern Mindanao.”

“This bridge will connect Lanao del Norte to Misamis Occidental. The other is the Guicam Bridge in Zamboanga Sibugay, which shall connect Olutanga Island to the mainland of Mindanao.”

“In addition, travel to and from Clark Airport is now much faster and more convenient, with the inauguration of the 20-kilometer Airport-New Clark City Access Road in Pampanga.”

“We are in the midst as well of a ‘railway renaissance’. The Metro Manila Subway Project has logged significant accomplishments in its tunneling works.”

Additionally, other railway projects such as the MRT-7 and the North-South Commuter Railway are in progress.

He mentioned that government will make sure that the right of way issues are resolved in the most equitable, efficient, and expeditious manner, so that these will not get in the way of the infrastructure development.

As part of the LRT 1 Cavite Extension project, the route of LRT Line 1 in Metro Manila will be extended from Baclaran to Sucat in Paranaque City. This is expected to be open to the public within the year. After a few years, the route will further extent to Bacoor in Cavite.

He also reported that LRT 1 had an additional 76 new and modern trains. This upgrade will provide a faster and more comfortable commuting experience for passengers.

The recent reopening of the PNR Bicol Line is also a milestone achievement in the list of railway projects. This railway spans out to 100 kilometers from Naga to Legazpi.

President Marcos Jr. also talked about the improvement of the country’s airports and harbors for the benefit of travelers.

With the help of the private sector, the Ninoy Aquino International Airport is expected to improve and provide better services in the years to come.

“Soon, it will be capable of accommodating 48 flights per hour, servicing our ever-increasing local and international flight routes, and catering to more than 62 million passengers per year.”

“More than 70 airport and seaport development projects across the country have been completed, and another 350 ongoing projects are set to be completed by 2028.”

“Notably, the capacities of the Passenger Terminal Buildings of the General Santos Airport and the Bicol International Airport have been expanded by 300 and 500 percent, now catering to 2,000 and 1,600 passengers, respectively. Meanwhile, the Batangas Port PTB, our popular marine gateway to MIMAROPA, the Visayas and to Mindanao, can now accommodate 8,000 travelers at any given time.”

“Thanks to Congress, the Public-Private Partnership, as a crucial funding mechanism for big-ticket projects, is now institutionalized by force of law. PPP is seen to facilitate strategic investments and the timely development of projects under our Build Better More program, especially since around one-fourth of our flagship projects have been envisioned to be funded through this modality.”

He emphasized that the NAIA PPP will go down in history as being the largest and fastest approved PPP, as well as setting the standard in terms of transparency and competitiveness of the process.

“Through this partnership, our foremost aerial gateway is now primed for a revitalization. Once considered among the worst and most stressful airports in the world, it will soon be a world-class international airport that we can be proud of.”

Continuous innovation at the heart of MMD Sizers

The MMD Group has a rich history in innovation and design, having designed, manufactured and installed the first unique Twin Roll SIZER™ more than 4 decades years ago. Since then, MMD have maintained leadership in the industry through constant development and innovation of the original Sizer concept. The company was formed to address the National Coal Board's (NCB) need to prevent large lumps of coal from blocking belt conveyor transfer points. Many methods were tried, but the installation of a low height, and lightweight MMD SIZER™ at the first convenient transfer point in the system was almost universally adopted in NCB mines. This success led to further developments and the company's expansion into other areas of underground and surface mining and quarrying in the U.K. and eventually around the world.

Since the inception of the MMD Twin shaft MINERAL SIZERSTM, MMD has thrived on a culture of innovation and continuous improvement, setting new standards in material handling and providing tailored mining solutions. Initially developed for processing coal, a softer and more brittle material, the range of Sizers has evolved to handle higher capacities as well as more abrasive, harder materials. This exceptional capability has resulted in the successful deployment of over 3,500 installations worldwide, serving small and large mining companies, who have some of the most challenging conditions and materials.

The basic design concept behind Sizer technology involve the use of two rotors with large teeth, on small-diameter shafts, driven at a low speed by a high torque drive system via a MMD reduction gearbox. Mineral Sizers exploit the inherent weaknesses in rocks. Sizers stand out from traditional crushing methods, because the unique tooth geometry breaks material by bending, tension, and shear forces. This approach delivers more efficient breaking action than alternative crushing methods, resulting in substantial savings in electrical power and overall operating costs.

An adjustable breaker bar, which is usually located beneath and between the twin shafts, provides the final stage of breaking. This maximises size reduction ratio, increases wear component life and provides complete control of the finished product size in all three dimensions.

The Sizer can accept minerals without the need for pre-screening. The scroll pattern of the teeth moves and re-orientates the larger lumps along the shafts for improved breaking. This creates space for undersized material to pass through freely without further wear or degradation. Additionally the scroll pattern can also be used to eject excessively oversize material from the machine.

The agitating action of its twin shafts also makes it ideal wet and sticky materials as well as ideal for blending scenarios, whilst minimising the generation of dust and fine material in primary, secondary or tertiary applications.

Innovation has always been part of MMD’s culture, and the dedicated in-house technical development teams has provided consistent research and development since the Sizer’s inception in 1980, and enabled MMD’s machines to process a wide range of material including some materials rated at over 300MPa. One key factor in maintaining our position as leaders is the ability to introduce the latest developments in the fields of design and production.

To ensure machines are designed to the highest standards our in house R&D teams bring a wide variety of experience in many fields of expertise. This diversity and experience are combined with some of the latest technology, from 3D design to material flow modelling. We use tools and methods such as:

Finite Element Analysis (FEA) - Finite Element Analysis is a way to simulate and analyse stress and deformation on a design. This provides the optimum design that is both efficient and effective.

Discrete Element Method (DEM) - DEM is particularly useful for modelling the behaviour of materials encountered in mining operations. By using DEM, we can analyse how these materials interact with various equipment and environments. This helps us design more efficient and durable machinery, reduce wear and tear, and improve overall operational efficiency.

Simulation - Simulation technology creates detailed models of our projects before they are built. By simulating different scenarios, we can predict potential issues and optimize designs for better performance and efficiency. This proactive approach helps in minimizing risks and reducing costs, ensuring that our projects are completed on time and within budget.

VR/AR - these immersive technologies provide 1:1 scale visualisations that can mimic real-world hypothetical scenarios. This helps virtual prototyping, HAZOP analysis and operative training. In addition these technologies also provide interactive project visualisations, providing clients with a better understanding of the equipment and the final outcome.

We also use physical prototyping and rigorous testing to validate the designs. Also, our close relationships with our customers provides us with continuous feedback loops to be able to incorporate practical insights and improvements.

Our continuous drive for delivering high standards is evident not only in the design but also through our five global state-of-the-art manufacturing plants in UK, Africa, China, Australia, and India. Each location has attained internationally recognized standards, and is ISO 9001 QMS certified. Environmental responsibility is also a priority; many of our global offices also hold ISO 14001 and ISO 45001 certifications.

Through our expertise, consistent investment in innovation and commitment to delivering high quality solutions through close partnerships, we can assist mines to achieve their efficiency and productivity goals whilst delivering a greener approach to mining.
