摘　　要：针对陕西榆林某煤矿主副斜井井筒在注浆处理后仍有较大涌水问题,在多种物探方法试验的基础上,选定地震映像法进行井筒壁及底板的探查,并结合已有钻孔及注浆成果资料开展评价,预测出井筒侧帮及底板存在地层介质破碎、松软以及空腔异常。经钻孔验证,地震映像取得的探测成果与钻探结果较为吻合。Aiming at the problem of large water gushing in the main and auxiliary inclined shafts of a coal mine after grouting treatment in Yulin,Shaanxi Province,the seismic imaging method is selected to explore the shaft wall and floor based on various geophysical exploration methods.Based on the evaluation of existing drilling and grouting results,it predicts that there are strata media breakage,looseness and cavity anomalies on the sidewall and floor of the shaft.After drilling verification,the exploration results obtained by seismic imaging method are in good agreement with the drilling results.
