LINE-X Industrial Coatings Modernize the Mining Industry for Enhanced Safety, Durability

by Philippine Resources - November 06, 2019

The global mining industry is on the rise with the help from pipeline activity, increases in mineral prices, changes to governmental mining policies and an increasing need for clean energy around the world. Strong output from some of the world’s most productive mines has generated several new opportunities in the industry. However, this kind of growth comes with added costs and an increased emphasis on mine safety to ensure compliance with current regulations and to build confidence in the mining workforce. Fortunately, companies like LINE-X are helping improve the mining industry using mining-specific coatings that not only ensure compliance with specific safety regulations, but also by helping lower operating expenses by increasing the sustainability of mining equipment.

Challenges Facing the Mining Industry

There is no doubt, mining is a dangerous job with several risks associated with poisonous and explosive gases and the use of dangerous explosives during blasting operations. Because of these hazards, mines rely on quality ventilation sealants like LINE-X, which have become critical to the safe operations of mines.

For years, mining companies have used various sealant materials that are effective but can deteriorate over time. These sealants prevent methane gases from escaping into working areas where it can mix with oxygen, causing it to become combustible and a potential deadly hazard to miners.

LINE-X Durability Solves Problems

Several years ago, mining engineers began looking at different materials that could be used to help seal ventilation systems and, in their research, they discovered that LINE-X’s spray-on polyurethane/polyurea hybrid coatings made excellent sealants for ventilation systems.

LINE-X then went on to develop LINE-X a polyurethane/polyurea hybrid spray-on coating with fire-retardant properties that forms a monolithic membrane to minimize the effluent gaseous migration in working areas. This unique coating from LINE-X is designed specifically for the mining industry with fire-retardant properties; therefore, it can be used on all Mining Safety and Health Administration (MSHA) underground ventilation controls of all shapes and sizes. Solidifying its fire-retardant properties, the MSHA has accepted this coating under its Standard Application Procedures for Acceptance of Flame-Resistant Solid Products. Because of its polyurethane/polyurea hybrid construction, this one-of-a-kind coating from LINE-X was the first of its variety to receive its acceptance.

Prior to the MSHA certification, LINE-X met, and exceeded, the specifications for the British Flame Spread Standard BS 476 (Part 7). This is a method for classification of the surface spread of flame to products when tested by Bodycote, an independent material testing company. The coating was found to have satisfied the requirements for a Class 1 rating per the BS 476 (Part 7). Furthermore, LINE-X was also tested per ASTM E-162’s “Surface Flammability of Materials Using a Radiant Heat Energy Source” and was found to exhibit an impressive flame-spread index. Naturally, this is extremely difficult and is one of the most challenging flame-spread tests in the industry.

LINE-X – A New Standard in the Mining Industry

Word has quickly spread that LINE-X’s polyurea coatings are becoming the new standard in protection in the mining industry. Not only are they designed to protect against impacts, abrasion, corrosion and other hazards found in mining operations; they also feature fire-retardant properties. How does LINE-X accomplish this? Simple — the mining-specific coating is self-extinguishable, thanks to its high-performance elastomeric polyurethane construction. Like many other LINE-X products, it can be applied to any type of underground equipment, no matter the shape or size. Additionally, LINE-X can prolong the life cycle of mining equipment by protecting the equipment from unwanted damages; resulting in less downtime and reduced maintenance costs.

Throughout the global mining industry, LINE-X‘s polyurethane/polyurea spray-on coatings are used on a variety of materials and applications. For mine seals, a low-pressure castable polyurea adhesive is used. Its chemistry is formulated to provide extremely high tensile and tear strength properties possessing 100% solid and containing zero VOC’s (volatile organic compound). This product is ideal for providing adhesion between concrete blocks when constructing a mine seal.

Example 1: Since 2010, LINE-X has been used as a battery box insulation for use in underground mines to prevent the spread of fire due to worn or damaged battery systems that can either self-ignite, or spark, increasing the possibility of the combustion of methane or coal dust.

Example 2: In the processing industry, LINE-X coatings are used for internal tank linings. These massive tanks are used to shred iron ore and over time, abrasions from metal-processing can break down the tanks, causing corrosion and degradation and ultimately shortening their lifespan. The solution was LINE-X – its resistance to abrasions and chemicals created an incredibly durable barrier that prolonged the life of the tanks allowing them to endure the continual movement of the iron ore.

Example 3: To increase the durability of mining equipment, chutes, hoppers, tools, sand- and gravel-equipment, LINE-X is being used as sacrificial liners in these types of environments to help increase the durability and service lifecycle of these types of equipment.

Real-World Results When LINE-X is Put to the Test

In a recent case study, a vermiculite mining company's shaker tables had become very degraded due to the severe abrasion issues caused by regular mining operations. These 8x25-inch shaking tables needed effective and durable protection from the irreversible corrosion and degradation caused by the harsh abrasions that occur from continual exposure to rock and slurry.

The first solution was a paint-like plastic product which failed quickly after regular use. So instead of continually replacing the plastic product when it failed, the company determined a protective coating that would permanently adhere to the surfaces was the only solution that could protect against constant corrosion, abrasion and impact.

To start the process, the company delivered all its shaking tables to its local LINE-X shop, where LINE-X immediately got to work disassembling, sanding and prepping substrates to removing any foreign substances and previous paint work. Next, the tables were completely encapsulated with one of LINE-X’s most durable polyurethane/polyurea hybrid spray-on protective coatings.

After allowing for a compete cure time, the results speak for themselves. LINE-X's superior spray-on protective coatings provide excellent resistance to the impacts and abrasion against rock and slurry damage during the shaking process. One of many benefits of LINE-X includes an extended lifecycle of the shaker tables that includes reduced downtime and overall better cost effectiveness.

Historically, mining has been one of the most dangerous and harsh industries in the world but through the use of scientifically-engineered coatings from one of the world’s leading pioneers of polyurethane/polyurea coatings, miners and mining companies are able to operate safer and more efficient mines.

Semirara Mining Expects Profit Recovery This Year

Semirara Mining and Power Corp. (SMPC), a publicly traded integrated energy firm, expect some profit recovery this year, owing to improved coal and power demand and costs. SMPC chairman and CEO Isidro Consunji said at the company's virtual stockholders' meeting that the company's bottom line will boost as the coal and energy markets rebound from last year's historic lows. “To take advantage of the upswing, we will capitalize on our COVID-19 resiliency and adaptation strategy of focusing on our people, finances, and execution skills. However, given our operational headwinds and until our country reaches herd immunity, it is unlikely that we will return to our pre-pandemic profit level this year,” he said. The business ended in 2020 with a combined net income of P3.3 billion, down 66% from P9.6 billion the previous year. Revenues dropped 36.2 per cent to P23.3 billion as coal production, sales, and prices fell, while energy sales fell due to low power rates and Southwest Luzon Power Generation Corp's (SLPGC) expected and unplanned outages. The coal division of SMPC and the SLPGC plants will be the key drivers of development this year. With remedial steps introduced in Molave North Block 7 (NB7), the coal industry is expected to reach 13 million metric tons, according to SMPC president and COO Maria Cristina Gotianun. “This year, we expect our coal business to perform better on the back of recovering consumption and prices. The remedial measures we have been implementing since December have also allowed us to steadily normalize production. Now that the water seepage at NB7 has gone down to manageable levels, we expect annual production to hit 13 million metric tons,” she said. Due to excessive water seepages, SMPC postponed mining operations in Molave NB7 in early December, reducing coal output by 13% to 13.2 million metric tons. SLPGC is expected to drive profits in SMPC's power market due to higher sales, but Sem-Calaca Power Corp. (SCPC) is expected to produce poor performance. SCPC is the owner of the Calaca coal-fired power plant in Batangas, which it bought from the government in 2009 for $362 million. In the same location, SLPGC operates a 2x150-MW coal power plant. “For this year, we expect uneven results from our power subsidiaries. SLPGC is set to stage a strong profit recovery because of higher plant availability and better spot market prices. Unfortunately, SCPC is likely to deliver disappointing results because of the forced outage of its Unit 2 beginning Dec. 3 last year,” Gotianun said. SCPC's outage was triggered by a seven-month-old generator stator failing. Repairs are currently being negotiated with generator provider GE, according to Gotianun. “While they have agreed to cover the majority of the costs related to fixing the equipment, we are intent on making them shoulder all the necessary expenses. We expect to complete our negotiations within the year,” she said. “In the meantime, we are doing our best to fast track the repair of the generator. If all goes well, Unit 2 can be up and running by the third quarter of this year,” Gotianun said. This year, SMPC will invest P4 billion to rebound from last year's slump. The overall sum will be divided between SCPC and SLPGC for their prevention and repair services, with P2.9 billion going to buy mining and service equipment for the coal industry. Since the COVID-19 pandemic placed a burden on the company's liquidity last year, the management agreed to delay P3.7 billion of CAPEX to this year as part of its cash saving steps.

Australian Mining Firms Show Interest in the Philippines

According to Australia's Ambassador to the Philippines, Steven Robinson, several Australian mining firms have shown interest in mining in the Philippines, and the recent lifting of a nine-year ban on new mining ventures has paved the way for the possibility of responsible and world-class mining. Robinson said that mining if conducted safely and in accordance with international standards, could help the Philippines recover from the effects of the pandemic's economic impact. “The miners that we already have here—Orica [Philippines], OceanaGold, Red 5 [group], a number of them—are already thinking about what the future holds for them as a result of that ban being lifted,” he said in a virtual briefing on Monday. “They have started to reach out to us just in recent times to express interest in mining across the Philippines. I think that is a very positive step for the Philippines and good for Australian miners here,” he added, when asked to comment on the lifting of the ban. Malacanang recently released Executive Order No. 130, effectively lifting the nine-year ban on new mining deals. The order reversed a clause of then-President Benigno Aquino III's Executive Order No. 79, which was issued in 2012. The EO included a clause prohibiting the issuance of new mining licenses or mining output sharing arrangements unless a new revenue-sharing scheme was established. President Rodrigo Duterte said that the mining tax scheme included in the Tax Reform for Acceleration and Inclusion (TRAIN) Act had already met the EO's requirements. The TRAIN Act increased the excise on minerals, mining goods, and quarry services from 2% to 4%, lowering personal income taxes while increasing consumption taxes. Duterte previously stated that the country had only used about 5% of its natural wealth. According to the Australian ambassador, this demonstrated that there was something that could be achieved in the world to assist in its economic recovery. “The Philippines is a natural resource-rich country, and there’s much that could be done here that will really benefit the Philippines’ recovery, and Australian firms know that,” Robinson said.

AC Energy Focuses on 12GW of Renewable Energy Projects

AC Energy (ACEN) is operating on approximately 12 gigawatts (GW) of renewable energy (RE) projects, more than double its goal of five GW for 2025, as it strives to become Southeast Asia's largest listed RE network. At COL Financial's briefing, ACEN President and CEO Eric Francia said the 12GW of projects placed the Ayala-led company in a fantastic position to achieve its long-term goals. Solar and wind platforms will make up the majority of the projects it plans to begin in 2021. With 5,200 megawatts (MW), Australia leads the way, followed by the Philippines with 3,400MW, Vietnam with 2,400MW, and India and other Asia-Pacific countries with 900MW. 1,000MW of the 12GW projects in the pipeline are expected to reach financial close in the next six to twelve months, bringing the company more than halfway to its target. By the end of the year, ACEN hopes to obtain regulatory clearance for the influx of foreign funds. The Ayala Group's power arm is maintaining a follow-on offering (FOO) until Friday, with shares priced at Php6.50 per share. “We are grateful for the continued support of our regulators and for the overwhelming response we received from the institutional investors during the book-building process. The exceptional investor support reinforces AC Energy’s position as the region’s leading renewables platform,” Francia said in a statement disclosed to the Philippine Stock Exchange. The FOO is part of a five-step effort by the company to generate Php30 billion for clean energy programs this year. “The FOO completes the company’s successful fundraising efforts this year and allows it to play a meaningful role in the green-led recovery,” Francia added.
