摘　　要：从地应力和瓦斯等方面系统分析了石门揭煤突出规模最大和危险度最大的根本原因:瓦斯来源最广而且地应力储集最大。介绍了近年来开发研究的两大卸压增透利器:水力割缝,水力压裂。通过对几个矿的实践,发现卸压增透措施相比常规措施效果显著,为有效防止煤与瓦斯突出、特别是防止石门揭煤突出发挥了重要作用,同时,采掘速度大大加快,提高了经济效益。The root causes for the great risk uncovering coal in cross-cut from the ground stress and gas,and other aspects are systematically analyzed: the gas source is most extensive and ground stress reservoir is the largest relative to other coal mining projects.Two powerful tools for pressure relief and increasing permeability,developed in recent years are introduced: hydraulic slotting and hydraulic fracturing.It is found that the effects of pressure relief and increasing permeability are obvious,important to efficiently prevent outburst for uncovering coal in cross-cut,and the economic benefits can be improved with the speeding up of the mining.
