Methane emissions from coal mines Source Reduction
Jan 07, 2022GHG effects from U.S. coal mining methane declined by 170 Mio t CO2-eq. from 1990 to 2005. About 15 projects are in operation at active mines, and more than 20 in abandoned mines. The gas is used for mine heating, pipeline injection and power generation. Gas sales generate about US$ 90 Mio in revenues annually.

Methane Emission in Coal Mines--the Effects of Oil
A recent detailed study by the Bureau of Mines of the effects of water infusion on methane flow in a coal mine revealed that while the rate of emis- sion appeared to decrease with distance from the face, actual measured con- centrations of methane fluctuated markedly about the average.

Environmental impact of coal mine methane emissions
Jan 01, 2011Methane emissions involved with the process of coal mining include several sources ( U.S. EPA, 2008 ): • Degasification systems at underground coal mines (also commonly referred to as drainage systems). • Ventilation air from underground mines, which contains dilute concentrations of methane. •

Methane Emission in Coal Mines: Effects of Oil and Gas
Emission rates were influenced markedly by the presence of abandoned oil and gas wells in the vicinity of the mine. Such wells appeared to increase the flow rate of methane into the mine by a factor of 2 to 30 in an active mine in the Pittsburgh coal seam.
