Coal Mine Methane: A Review of Capture and Utilization ...

2012-8-30  Coal mine methane has always been considered as a danger for underground coal mining as it can create a serious threat to mining safety and productivity due to its explosion risk. One of the most important duties of ventilation in underground coal mines is to keep methane levels well below the explosive limit by diluting methane emissions that occur during mining.

Assessing Emissions from Active and Abandoned Coal

2021-6-16  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. As a consequence, a large amount of gas migrates into the mine and is exhausted to the atmosphere with ventilation air.

Methane from Coal - PA.Gov

Methane from Coal. The natural gas methane is a byproduct of coalification -- the process where plant materials were gradually buried, compressed, and heated, resulting in the various ranks of coal. In Pennsylvania, natural gas is extracted from coal as coalbed methane and as coal mine methane. Coalbed methane comes from virgin (unmined) coal.
