针对大埋深高瓦斯低渗透煤层的安全快速揭煤问题，采用钻割一体化卸压防突技术，运用FLAC3D软件模拟了钻割的过程，分析了不同钻割直径和不同钻割间距时煤体的卸压影响范围，为进一步确定钻割技术参数提供依据。
針對大埋深高瓦斯低滲透煤層的安全快速揭煤問題，採用鑽割一體化卸壓防突技術，運用FLAC3D軟件模擬瞭鑽割的過程，分析瞭不同鑽割直徑和不同鑽割間距時煤體的卸壓影響範圍，為進一步確定鑽割技術參數提供依據。

For rapid and safe uncovering in high-gas low-permeability seam with large buried depth, outburst prevention for drilling-cutting integration pressure relief was adopted. FLAC3D simulated the drilling and cutting process and analyzed the pressure relief influence at different drilling diameters and different drilling intervals, which could provide data for further determination of the drilling technology.
