潘北矿分段水力压裂增透技术研究

Experimental Study on Hydraulic Fracturing and Penetration Technology in Panbei Coal Mine

在潘北矿开展了分段水力压裂增透技术试验,通过设计分段水力压裂钻孔组与未采取水力压裂的考察钻孔组进行对比试验研究,结果表明:采用了分段水力压裂钻孔组其关键指标参数远高于未采取水力压裂的考察钻孔组,试验取得了预期效果,极大地有利于矿井的瓦斯治理。

Carried out the sub-hydraulic fracturing and penetration technology experiment in Panbeimine. By designing the sub-hydraulic pressure, the gas pressure of the gas-permeable coal seam haslong been one of the bottlenecks of mine safety production. The results show that parameters of the keyindexes used in the fractured hydraulic fracturing drilling group are much higher than those withouthydraulic fracturing to study the drilling group, the test achieved the desired effect, which greatly favorsthe mine gas control.
