Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.

Jul 25, 2018· Acid Mine DrainageEven careful mining practices can take a hefty environmental toll through secondary pollution effects like acid mine drainage. Acid mine drainage, or AMD, occurs when sulfide-rich rocks that contain target ores like gold and copper are exposed to water and air. The sulfides form sulfuric acid, which dissolves surrounding rock, releasing harmful metalloids into the groundwater ...

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash.Any material that cannot be grown through agricultural processes, or created artificially in a laboratory or ...

Mining coal generates 40 g, on average, of float coal dust per ton of coal mined. Most of this float coal dust is deposited at or near the working sections. The possibility of methane ignition is also high at the working faces due to methane liberated from newly exposed coal face and possible frictional sparks generated in mining process.
