摘　　要：9103工作面位于15#煤层采空区上方,为了分析15#煤层开采对上覆9103回采工作面底板稳定性影响,采用钻孔渗漏法对15#煤冒落带、裂隙带高度进行探测,并用钻孔窥视方法验证,结果表明:15#煤层裂隙带、冒落带发育高度分别为10.41 m,4.11 m,9#煤层底板下方仍有约20.48 m厚稳定岩层,预计15#采空区不会给9#煤层开采带来不利影响。In order to analyze the effect of No.15 coal seam mining on the floor stability of the overlying 9103 mining face,the author proposes the borehole leakage method to detect the heights of caving zone and fracture zone and verify with borehole peeping method,whose results show that the developmental height of fracture zone and caving zone are 10.41 m and 4.11 m respectively,with 20.48 m-thick stable rock layer under the floor of No.9 coal seam and no adverse effects of No.15 goaf on No.9 coal seam mining.
