淮南潘一煤矿未开拓区煤与瓦斯突出预测

淮南矿区是瓦斯事故重灾区,潘一矿进入-400m水平开采以来,共发生25次煤与瓦斯突出,严重制约了该矿的生产安全。利用已采区瓦斯地质实测成果,结合未开拓区煤田地质勘查资料,对该矿13-1煤层瓦斯压力和含量、煤的力学性质、煤层受力状态进行了分析,提出了13-1煤层未开拓区煤与瓦斯突出预测指标,并对未开拓区煤与瓦斯突出危险区进行了预测。结果表明煤与瓦斯突出危险区主要分布在位于F34断层附近、F38断层-钻孔V-3一带、F125-Fs107-Fs106附近、Fe7-Fe1之间的部分区域及F4断层西南端部分区域。

Coal and Gas Outburst Prediction in Undeveloped Area of Huainan Panji No.1 Coalmine

The Huainan mining area is a bump-prone area, 25 times of coal and gas outburst had happened since the Panji No.1 coalmine opening-out into -400m level, thus restrict production safety seriously. Using gas geological tested data from mined areas, combined with undeveloped area coal geological exploration data, analyzed gas pressure and content, coal mechanical property and coal seam strained condition of No.13-1 coal seam in the coalmine, coal and gas outburst predicting indices of undeveloped area have been brought forward and outburst hazardous area predicted. The result demonstrated that the coal and gas outburst hazardous area is mainly distributed near the F34 fault, F38 fauh-borehole V-3 district, F125-Fs107-Fs106 near by, some part between FeT-Fel and some part of F4 fault southwestern end.
