PROSPECTS OF COAL MINE METHANE UTILIZATION

During coal mining methane is extracted to the surface by degassing, ventilation, and gas release control systems. Methane is a greenhouse gas, but at the same time is suitable for beneficial use. The article estimates the volumes of methane emissions that accompany underground coal mining, the concentrations of methane in the methane-air mixture depending on the types of emission sources. The paper considers the major aspects and possible ways of utilizing coal mine methane for producing useful products, heat and electric energy, as well as motor fuel.
