Unlocking the Potential of Coal Mine Methane in China

Nov 04, 2013On Saturday an explosion killed 7 coal miners in China's Guizhou Province; another in a long history of fatal coal mining accidents in China. Explosions like this are typically caused by the release of highly volatile, low-concentration methane. During coal extraction, Coal Mine Methane (CMM), which is trapped in the coal seam, is released into the air supply.
