针对我国矿井超前钻探探水存在工期长且成本高的问题，探讨瞬变电磁法超前预测预报矿井作业点水害的可行性。以贵州省坪土煤矿1502回风石门掘进工作面为例，通过使用瞬变电磁探测仪对坪土煤矿1502回风石门迎头进行探测，探明该回风石门迎头有3处相对低阻区域，阻值均在10～20Ω· m，无大的水体和裂缝带。根据现场施工的验证，钻孔显示该区域无大的水体及含水层，水文情况较为简单，只有小裂隙存在小量的裂隙水。实际钻探情况与探测结果一致，表明了瞬变电磁法探测矿井作业点水害的可行性。

In order to solve the problem of long project time and high cost in advance drilling water in China , the feasibility of transi-ent electromagnetic method in forecasting water disaster was discussed.Taking driving air-return crossheading face as an example , ap-plying transient electromagnetic exploration equipment , 3 relative low resistivity ( 10 ~20Ω· m ) zones ahead of face were ob-tained.Actual construction showed that there was no large water body and aquifer in this area , hydrologic condition was simple and there were only small fissures and a little water.This proved that it was feasible for transient electromagnetic method applied in forecas -ting water disaster.
