Unevenness of gas emission within the mining area
Abstract
Methane emission within the excavation area depends on the operation of mining machines, atmospheric pressure fluctuations, collapse of rocks of the main roof, irregularity of air supply, etc. Regardless of the influence of these factors, the methane content in the outgoing jet of the site should not exceed 1%. Consequently, it is necessary to supply to the site such amount of air Qpred that would ensure compliance with the requirements of Safety Rules at any combinations of these factors.
