Abstract:
In view of uneven gas distribution and local gas accumulation in Zhaoguan Coal Mine, from regional coal field to mine geology and then to mine gas geology, the gas accumulation area and gas occurrence characteristics in Zhaoguan Coal Mine are described by applying the gas geology control theory step by step. Through the comprehensive analysis of the main controlling factors affecting the gas occurrence rule of Zhaoguan Coal Mine, the buried depth of coal seam, the intruding condition of magmatic rock, the basic form of fault and the lithology of the roof and floor of coal seam are the main factors affecting the gas occurrence rule, and the corresponding technical measures for regional gas disaster prevention and control are proposed.
