Technology of Efficient Recovering of Highly Concentrated Methane and Mechanical Impurities from Ventilation and Degasification Emissions from Coal Mines

摘要

The article deals with the technology of efficient recovery of highly concentrated methane and mechanical impurities from ventilation and degasification emissions from coal mines using the effects of energy vortex gas separation of methane-air mixtures, in which the content of methane does not exceed 1-2%. It is particularly true with ventilation emissions, where the content of methane is 0.2-1%, and currently, due to unavailability of efficient equipment, methane is not recovered, but is emitted to atmosphere in the form of greenhouse gases, which leads to negative environmental impacts. The article sets forth the approaches and engineering solutions for preventing harmful emissions.
