The long wall excavation method in mining is a highly efficient technique primarily used in coal mining, involving the full extraction of large rectangular coal blocks in a continuous operation. Using a long wall face, typically 100 to 300 meters long, hydraulic roof supports, or shields, hold up the mine roof while a shearer or plow cuts the coal. The coal is transported to the surface via a conveyor belt. As the shearer advances, the supports move forward, allowing controlled roof collapse, known as caving. The method has notable environmental drawbacks. Subsidence from the controlled roof collapse can cause ground movement, damaging ecosystems, water bodies, and infrastructure like buildings and roads. This can disrupt drainage patterns and contaminate groundwater. What is your view on this method? Comment below.

New soil sampling assays have enabled Intra Energy Corporation (ASX: IEC) Ltd to define a large-scale, high-tenor #gold anomaly at the Maggie Hays Hill (MHH) Project in Western Australia with gold values between 15 and 85 parts per billion. Infill soil sampling conducted in May has defined a 700-metre-long and up to 170-metre-wide gold anomaly at the 80%-owned project which the company is planning to test in an upcoming drill program. The sampling was conducted to follow up a broad +1.5-kilometre-long gold anomaly that occurs along the sheared contact between a basalt and ultramafic unit. Field mapping identified quartz reefs occupying dilational jogs along the shear zone and these are strongly correlated with the elevated gold results.

As governments globally push for regulations limiting sand extraction, the shift towards artificial sand, produced by crushing granite or basalt rocks with crushing equipment, is accelerating. Hydraulic breakers play a vital role in this process by breaking down large rocks into smaller ones, facilitating the production of artificial sand. Consequently, the growing demand for crushing equipment is anticipated to drive the market for hydraulic breakers in the forecast period. 𝗧𝗼 𝗞𝗻𝗼𝘄 𝗗𝗲𝗺𝗮𝗻𝗱 𝗼𝗳 𝗛𝘆𝗱𝗿𝗮𝘂𝗹𝗶𝗰 𝗕𝗿𝗲𝗮𝗸𝗲𝗿𝘀 𝗠𝗮𝗿𝗸𝗲𝘁.

Discover innovative solutions in the mining industry! We're proud to introduce ORESORB™—a patented hydrogel designed for underground blasting and dust suppression. It not only improves blasting efficiency but also enhances the safety of miners. During the production process of open-pit mines, a significant amount of dust is generated at every stage, from drilling to loading, transportation, crushing, and soil discharge. Our SOCO® products have achieved positive results in countries like Australia, India, France, Brazil, and more. 🌏 ORESORB™'s excellent water absorption and retention capabilities allow it to be adsorbed for a long time at room temperature, penetrating gaps between dust particles. By increasing the mass of dust particles through moisture absorption and promoting coagulation through adhesion, it effectively suppresses dust dispersion. In blasting operations, ORESORB™ serves as a blast hole sealing agent, rapidly forming a solid hydrogel to effectively seal the blast hole, reducing the pressure shockwave from explosions, and regulating gas pressure to decrease noise and dust emissions. Moreover, ORESORB™ is also applicable for dust suppression on mining roads, slope greening, loose material piles, and dust suppression and sludge solidification in mining tunnels. 🌳 Join us in promoting green development in the mining industry and creating a safer and more efficient working environment! 🏭 https://lnkd.in/gfZRXR_P #DustSuppression #MiningInnovation #ORESORB #SafetyFirst #GreenMining #BlastingTechnology #EnvironmentalSustainability #MiningSafety #IndustrySolutions

Using waste rock as backfill in mining operations can have several economic advantages that can lower overall mining costs and effectively reduce the cutoff grade needed to make a mining project viable. Here are some key points explaining how this works: 1. Reduction in Waste Management Costs: - Minimizing the Need for Disposal: By utilizing waste rocks as backfill, mining companies can avoid the costs associated with transporting and disposing of waste material. This reduces the need for waste rock storage facilities, which can be expensive to construct and maintain. - Maintaining Land Use: By backfilling pits with waste rock, companies can minimize land use and environmental impact while potentially avoiding regulatory costs related to waste management. 2. Decrease in Land Rehabilitation Costs: - Stabilization of Mine Sites: Backfilling helps stabilize the mine site, reducing the long-term costs associated with land rehabilitation and remediation once mining operations cease. - Easier Rehabilitation: Using waste material for backfilling can lead to more straightforward rehabilitation strategies, since the mined land can be restored more easily if it has already been filled and stabilized. 3. Improved Resource Recovery: - Increased Extraction Efficiency: Backfilling can allow for more efficient resource recovery. When waste rock is managed properly and used to support mine workings, it can create opportunities to mine lower-grade ore which, otherwise, would not have been economical to extract. - Optimizing Mining Operations: By using waste rock to provide structural support, mining operations may be able to operate in a more flexible manner with larger mining sequences and lower operational risks. 4. Lower Transportation Costs: - Cutting Haulage Needs: Using waste rock locally reduces the need to transport backfill material from other sites, leading to notable savings on transportation costs. These savings can further decrease the overall operational costs of mining. 5. Economic Impact on Cutoff Grade: - Redefining Economic Viability: The reduction in overall operational and management costs allows for a reassessment of the cutoff grade, which is the minimum grade at which a particular mineral can be economically mined. Lower mining costs enable the feasibility of mining lower-grade ores, thus enhancing the overall resource base that is economically extractable. - Increased Flexibility: By lowering the cutoff grade, mining companies can decide to extract ores that were previously considered uneconomic, thus increasing the total recoverable reserves and potentially improving the mine's overall profitability.

Open pit and mining face surface water and groundwater management is one of the critical areas to put emphasis on, failure to do so can lead to. 1. Hauling trucks Tyres early wearing. 2. Trucks and excavator components damage. 3. Ore grade dilution. 4. Increased circle times and fuel consumption. 5. Compromise ore Tonnes (more Tonnes due to added water weight). 6. Failure of pit walls. 7. Compromise overall planning (some blocks have to be skipped in order to ensure dry and continue mining). 8. Mine unplanned stoppages, due to unavailability of mining faces. 9. Production Cost increase due to spare parts, downtimes, dozing chemicals in process plant due to increased water content in the ore, increased fuel consumption, increased circle times etc. Then, what has to be done? 1. Ensure storm water management plan is in place and updated before the start of wet season. 2. Correct use of both Active and Passive dewatering systems. 3. Proactive planning schedules, especially during the wet season to incorporate the risks associated. 4. The use of adaptive mining methods like Sequential drop cuts can become of handy. 5. Reverting back to conceptual and numerical models established for specific pits. Supported by simulations and other predictive methods for short-term and long-term planning. 6. General monitoring. #openpitmining #Hydrogeology #surfacewatermanagement #Dewatering #Modelling
