The Analysis of Gas Dynamic Hazard
Shanxi Maijie coal was private formerly and was integrated in 2006,whose production capacity rises from 0.3 Mt/a to 0.9 Mt/a.Maijie coal plan to take gas extraction,so we need to investigate gas situation and confirm whether it is necessary for that.This article will from the views of coal seam,coal mining and development and gas emission to judge the necessity of gas extraction with the gas concentration distribution,the isoline gas content and gas emission calculation.According to coal mine safety regulation and coal mine gas extraction engineering design specifications serious analysis,Maijie coal need for gas extraction to meet 0.9 Mt/a output.
Maijie coal merging and reorganization gas content gas emission gas extraction necessity
