Assessing Emissions from Active and Abandoned Coal Mines

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.

Greenhouse Gas Emissions From Coal Mining Activities and

Jan 01, 2018 With very significant CO 2, CH 4, and N 2 O emissions from different mining activities as fugitive emissions, coal mining is a major contributor to the buildup of GHGs in the atmosphere. These gases allow solar energy to reach the earth's surface but delay that energy's escape into space, and thus effectively trapping heat in the lower atmosphere.

Jul 07, 2021 Metallurgical coal's carbon footprint will become increasingly relevant to a decarbonizing steel industry. Evident in the distribution of open-pit and underground mines, excavation type, and to a lesser extent mine depth and fugitive methane, drives variations in emissions intensity for metallurgical coal operations (Exhibit 2).
