摘　　要：为了科学评价候村煤矿峰峰组上段相对隔水性能,在补充地质勘探HC51、HC62号钻孔中采用水压式双段止水栓塞对其进行了压水试验,通过计算各试段岩体透水率和渗透系数从而判断峰峰组上段相对隔水层的分界,证明压水试验不仅可以适用于水利水电、坝基、桥梁隧道等工程地质勘查中,同时,也可以在煤炭地质勘查中对其进行应用。In order to scientifically evaluate the relative water repellency performance of the upper part of peak-peak group in Houcun Coal Mine,a water pressure test was carried out by using hydraulic two-stage water-stopping plugs in drilling holes HC51 and HC62 in supplementary geological exploration.The boundary of the upper part of peak-peak group relative water-resisting layer was judged by calculating the permeability and permeability coefficient of rock mass in each test section,which proved that the water pressure test can be applied not only in engineering geological exploration of water conservancy and hydropower,dam foundation,bridge and tunnel,but also in coal geological exploration.
