摘要
潘北煤矿在副井揭穿B8强突煤层时,采取了井筒四周钻孔连续抽放瓦斯与水力冲孔综合治理技术,有效地消除了强突煤层的突出危险性,使副井安全揭过B8煤层,实现了立井揭穿大倾角强突出煤层技术,可供类似矿山参照实施。
Drilling hole around shaft drawing out gas and hydraulic releasing technique were used when uncovering B8 coal seam in Panbei Coal Mine. This method removed the outburst danger of forceful outburst coal seam and made the auxiliary shaft cross B8 coal seam safely. It was realized that shaft uncovering large degree of dip forceful outburst coal seam technique, which can provide reference for other mines.
