- W2372727747 abstract "Based on the research on gas geological characteristics of 7 coal and gas outburst mines,12 high gas mines and 32 low gas mines in Hebei province,the plate structure gas occurrence theory was proposed.North China plate tectonics control the gas distribution of Hebei provenice,and the distribution of gas in each mine is controlled by regional structure.The gases in the mining areas and mining faces are controlled by mine structure.The mining area in Hebei province is divided into four high gas zones including northwestern of Kaiping coal field,Xiahuayuan-Babaoshan area,eastern of Gu Mountain in deep of Handan-Xingtai coal field and Xinlong-Kuancheng-Songshutai cities.The research results show that the distribution of high gas in outburst mine with zoning characteristics is controlled by fold belt of EW-trending Yanshan Mountain and NNE-trending structural belt of Taihang Mountain.For deep fault and groundwater,gas is low in the southwestern part of eastern Taihang Mountain and high in the northeastern part of eastern Taihang Mountain.The Yanshan fold belt developed thrust nappe structure for NW-SE trending horizontal direction squeezing action in Yanshanian epoch.The imbricate distribution of coal caused by intensive development of reverse fault is beneficial for gas preservation.80% of coal-bearing strata in the mines are carboniferous and permian.The gas outburst fatalities of carboniferous and permian are greater than those of jurassic." @default.
