超化煤矿高瓦斯高应力煤巷掘进面瓦斯治理

Gas Management of High Gas and High Stress in Driving Face of Coal Tunnel in Chaohua Coal Mine

超化煤矿在”三软”厚煤层高瓦斯高应力突出危险区域进行了综合消突技术的尝试。实践证明,深孔卸压抽放和浅孔静压释放瓦斯相结合,是超化矿高瓦斯高应力区域煤与瓦斯突出防治行之有效的方法。

Try of the synthesis eliminating outburst is carried in high gas, high stress, outburst and dangerous district at ＂three soft＂ thick coal seam in Chaohua Coal Mine. The combination of gas drainage with deep hole pressure relief and releasing gas with shallow hole static pressure is an effective way of prevention and cure of instantaneous of coal and gas in high gas and high stress district in Chaohua Coal Mine.
