水力割缝技术在平煤八矿14140底抽巷的应用实践

Hydraulic Cutting Seam Technology Application Practice of 14140 Bottom Exhaust Drift in No.8 Coal Mine of Pingmei

结合平煤股份八矿己15-14140底抽巷水力割缝前期钻孔施工现状,实测考察钻孔瓦斯浓度前后变化数据,初步考察水力割缝效果,对己15-14140底抽巷水力割缝目前存在的不足提出相应的整改措施和意见。

Based on Pingmei shares No.8 coal mine Yi15-14140 has bottom alley pumping hydraulic cutting seam prophase borehole construction situation,inspect drilling gas concentration measurement data changed before and after preliminary examination hydraulic cutting,sewing effect,and Yi15-14140 bottom alley pumping water cut seam disadvantages forward corresponding rectification measures and suggestions.
