The Most Dangerous Gases In Mining: Damp Gases

Oct 23, 2019Firedamp is a mining term for a set of explosive gases found in mines. It's mostly made up of methane and methane is often an interchangeable term when miners talk about firedamp.

Assessing Emissions from Active and Abandoned Coal Mines

The gas emission zone liberates and accumulates significant amounts of coal mine methane as a by-product of active mining. In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone.
