中文摘要：
为了查明新安煤矿13-15采区岩溶径流带的分布,运用地质学、水文地质学知识初判岩溶径流带的大致方向;利用井下瞬变电磁技术,结合井下钻探资料、连通实验综合确定径流带位置和径流方向。结果显示,该技术成功探查出新安矿13-15采区存在一条岩溶径流带,该径流带走向为近SN向,与矿井内主要断层方向一致,以溶洞和溶孔为主,岩溶水自北向南径流。该技术对矿井岩溶径流带探查和矿井防治水具有一定的参考价值。
英文摘要：
To find out the distribution of karst runoff zone in 13-15 mining area of Xi＇an Coal Mine, general direction of the runoff zone was judged by analyzing geological and hydrogeological data; the location and direction of the runoff zone were confirmed by transient electromagnetic combining drilling data and connectivity experiment. According to the results, a karst runoff zone is in 13-15 mining area, the runoff zone strikes SN and is consistent with the main fault direction in the coal mine, which manifests as caverns and dissolved pores, karst water runoffs from north to south. The technology has certain reference significance in the exploration of karst runoff in other mines and prevention of mine water.
