Huainan Xie 2 Mine is located in the Xiejiaji Mining Area in the middle of the Mt.Fugongshan Coalfield. There are totally 4 coal groups A, B, C and D in the coal measures strata, of which 13 layers can be adopted. The total thickness of the coal seam is 38.75 meters, the total recoverable thickness is 28 meters and the coal seam dip angle is 8 ~ 32 °, both of which are Permian stone box sub-systems and the coal type is gas and fat coal. Mine absolute gas emission 30 ~ 40 m ~ 3 / min, the relative emission of 30 m ~ 3 / t or so, for the super gas mine. Coal and gas outburst have occurred 6 times since the mine was built. Gas is mainly derived from
