Methane Explosions In Coal Mines

FOB Reference Price: Get Latest PriceGet Latest Price

In February 2016, 36 miners were killed by an unsuppressed methane gas explosion at the Severnaya coal mine in Vorkuta, Russia. In November 2016, 33 miners were killed due to an unsuppressed explosion in Jinshangou Coal Mine in Chongqing. The risk of a methane gas andor a coal dust explosion is clearly still present in coal mining operations.
