31.10.2021Methane is an unavoidable bi-product of coal mining, with gas released as seams are opened. In 2019 the US Environmental Protection Agency (EPA) estimated that 11% of all man-made methane emissions came from coal mining. As a build-up of methane can cause explosions in underground mines, operators monitor gas levels for reasons of safety.
