突出煤层“三岩两煤”瓦斯综合治理技术研究与应用

针对突出煤层瓦斯压力大、瓦斯含量高、治理难度大的问题，以平煤八矿22060工作面为例，探索突出煤层“三岩两煤”瓦斯综合治理技术，通过对穿层预抽、水力冲孔卸压增透、深孔打钻、封孔工艺、综合抽放等关键技术的应用研究，实现了突出煤层采掘工作面不掘突出头、不采突出面的目标。

Research and application of "three rock layers and two coal seams" gas comprehensive control technology in coal seam with outburst danger

Aiming at the problems of high gas pressure，high gas content，and gas control difficulty for coal seam with outburst danger，taking 22060 face of No.8 Coal Mine of Pingdingshan Tian′an Coal Industry Co.，Ltd.as an example，the authors made an brief discussion on the gas comprehensive control technology of outburst coal seam with "three rock layers and two coal seams". Through the application of key technologies，including layer-through pre-drainage，pressure-relief and permeability increasing with hydraulic flushing，deep boreholes drilling，hole sealing technics，comprehensive drainage hole technology，and so on，the goal of not mining when existing outburst danger on working face with outburst danger has been realized.
