Research on Gas Deposit Rules of Coal Pore Structure in Gas Outburst Area

WU Li-li,LUO Xin-rong,ZHOU Yun-han(Faculty of Safety Engineering,China University of Mining Technology,Xuzhou 221008,China)  
With outburst coal seam in Dingji Coal Mine of Huainan Mining Industry Group as test points,researches the coal seam pore by using pressure mercury testing method.The test results show that gas occurrence is different when pore radius is not the same,and free and adsorption gas content is different.On this basis,by high pressure capacity makes adsorption test of coal samples and combined with industrial analysis resuts,analyses the content of coal-bed methane adsorption,considers the effect of temperature on methane adsorption test according to the realities of Dingji Coal Mine,provides a basis for coal and gas outburst prediction.
