基于水力冲孔的瓦斯综合抽采技术研究

Research on Gas Comprehensive Extraction Technology Based on Hydraulic Flushing

在基于水力冲孔卸压增透措施的基础上,提出了穿层钻孔瓦斯综合抽采技术,即水力冲孔结合卸压带瓦斯捅孔抽采与采空区瓦斯抽采。首先研究了综合抽采措施的理论基础;其次,结合某矿实际情况,现场进行了应用;最后考察了瓦斯抽采情况与消突效果。结果表明,该技术获得了较好的抽采效果,消除了突出危险性。相关研究为类似矿井的消突方案提供了参考。

Use crossing hole gas comprehensive extraction technology based on hydraulic punching pressure relief and increase permeability, this method contains hydraulic punching pressure relief and increase permeability and distressed zone gas drainage and goaf gas drainage. First of all, research the theoretical basis of gas comprehensive extraction measures;then applied in the site based on physical truth of one coal mine;in the end,studied the gas extraction condition and the outburst elimination effect. The result showed that method obtains good extraction effect, the outburst dangerous was eliminated. This research shows similar coal mines useful reference.
