Remembering explosion in Redstone's Coal Basin Mine 40 ...
The Coal Basin mines were known to be "gassy." An explosion in 1965 killed nine men. Methane oozes from every face of newly cut coal and when it reaches 5% to 15%, a tiny spark will set it off. Great efforts were made to ventilate the mines and hold the methane down below 1%. Powerful 8 foot fans, were at the portals, forcing gales into the ...

Explosions in U.S. coal mines have caused death and injury to miners and destruction of workings since the first reported explosion in 1810. These explosions are caused when buildups of explosive gas and/or dust in the mine are ignited by the presence of a flame or spark. Methane gas is inherently generated and held by adsorption in coal and is ...

Explosions in underground mines and surface processing facilities are caused by accumulations of flammable gas and/or combustible dust mixed with air in the presence of an ignition source. While much progress has been made in preventing explosion disasters in coal mines, explosions still occur, sometimes producing multiple fatalities.
