  • Methane Explosions In Coal Mines

The Most Common Accidents in the Mining Industry

2019/1/14Methane and Consecutive Coal Dust Explosions Methane is a highly explosive gas trapped within coal layers. Mechanical errors from improperly used or malfunctioning mining tools (such as safety lamps or electrical equipment) or the use of improper explosives underground can trigger methane and initiate consecutive coal dust explosions.

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.
