摘要：
Coal and gas outburst is closely related to geographic structure which controls the preservation of the coal seam gas, the cracked degree and the thickness distribution of coal deformation and the occurring of coal and gas outburst. For the serious situation of coal and gas outburst in E 9-10 coal seam in Pingdingshan tenth coal mine, this paper analyzed geological structure control, the growth extent of deformed coal and the distribution of high-energy gas depositing based on the idea that the common areas of high-energy gas and deformed coal are easy to occur coal and gas outburst. The conclusions are that in E (9-10) coal seam the distribution law of gas depositing is distinct, the whole coal seam exists thicker deformed coals, high-energy gas controls the coal and gas outburst, the distribution of high-energy gas is equal to the distribution of gas outburst coal body, because of the control of NW-NWW distort structure belts.
