平顶山矿区高突煤层立体抽放安全高效回采技术的探索与实施

Exploration and implement of the technology of stereoscopic gas drainage and safe and efficient mining for the high outburst coal seam in the Pingdingshan coal mine area

针对平顶山矿区煤层开采深度大、瓦斯含量高、突出危险性大、煤层透气性低的特点,在首山一矿探索出了大采长一面多巷立体抽放瓦斯治理格局。通过抽放巷及本煤层快速掘进,为瓦斯治理创造了时间和空间,同时利用穿层钻孔和顺层钻孔立体抽放,实现了安全高效回采。

Aiming at the features of coal seam with deep mining, high gas, greater outburst danger, low gas permeability in Pingdingshan coal mine area, the gas treatment which was stere- oscopie gas drainage in the long working face with multi-roadway was explored in the Shoushan No. 1 Coal Mine. Speedy drivage of the gas drainage roadway and the working seam roadway provides time and space for gas treatment, and the stereoscopic gas drainage by boreholes down and cross the seam reaches safe and efficient mining.
