摘　　要：望云煤矿15号煤层开采后形成的导水裂隙带可能与3号煤层的采空区积水有沟通,威胁15号煤层安全生产,因此需要对15号煤层采后形成的导水裂隙带进行实测。通过井下网络并行电法进行现场实测,根据探测剖面的电性参数分布特性,分析煤层顶板岩层的变形和破坏规律,确定了垮落带和导水裂隙带发育高度值;15号煤层首采面垮落带发育高度实测值为18m,导水裂隙带发育高度值为71m;垮落/采厚比为3.83,裂缝/采厚比为15.11。The water conducted zone has been formed during coal No.15 extraction in the Wangyun coalmine,probably connected worked-out area ponding and threatening coal No.15 safety in production.Thus water conducted zone should be actually measured.Through underground network concurrent electric method has carried out site measurement.Based on prospecting section electric parameters distribution features have analyzed coal roof strata deformation and failure regularities,finally determined caving zone and water conducted zone developed heights.The results have shown that the measured coal No.15 first coal face caving zone developed height is 18m;water conducted zone height 71m;caving zone height/shear height ratio 3.83 and water conducted zone height/shear height ratio 15.11.
