    explosions, too, trigger casualties when ventilation systems fail to effectively remove exhaust from mining equipment, coal dust and natural underground gas leaks. blasting can ignite those gases, leading to deaths from both the explosions themselves and the subsequent collapse of mine structures; a methane-gas explosion killed those 29 miners in west virginia [source: macia ].

    What Is Underground Mining? (with Pictures)

    underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. this is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.
