摘要 针对西部某矿松软低透煤层,以含瓦斯煤层水力致裂裂隙内流场为研究对象,基于现场试验,结合理论分析等方法研究了低透气性煤层水力致裂裂隙内流场驱替机理。结果表明:水力压裂技术能够有效提高煤岩体的透气性及钻孔瓦斯抽采效果。 According to the soft and low permeability seam of a mine in west,taking the hydraulic fracturing crack internalflow field in gas bearing coal seam as the research object,based on field test, and combining with the theoretical analysis,studies on the displacement mechanism of internal flow field of low permeability coal seam hydraulic fracturing.The result shows, hydraulic fracturing technology can effectively improve the coal rock permeability and borehole gas drainage.
