Miners Lamp History from Flame to 'the Davy Lamp' to

With coal comes methane (CH4). Methane is explosive between 5 -15% and the naked flames were the ignition source. The recorded figures for a 10-year period between 1870 and 1880 were 2,700 miners (men and boys) losing their lives to explosions alone.

Coal Mine Methane

In fact, the methane leaks from the worst mines will cause almost as much warming as the direct CO2 emissions from burning coal, when measured over 20 years. The IEA calculates the CO2 equivalent impact of methane over a 100 years timescale, but they make explicit that the warming potency of methane increases from x30 to x85 vs. CO2 when measured over 20 years instead.

Identifying Improved Control Practices and Regulations to Prevent Methane and Coal Dust Explosions

In U.S. mines, methane is primarily controlled through dilution and methane drainage, while coal dust explosions are controlled by inertizing coal dust with (limestone) rock dust. In addition to these methods, other countries use both passive and active methane
