摘　　要：查明煤矿采空区积水边界,可以有效预防水害事故发生。利用矿井瞬变电磁探测技术,用同一台仪器在野川煤业井下选取已知区域进行探测,得出该矿井下瞬变电磁的电性规律,然后对野川煤业3103工作面回风巷外侧进行探测,圈定出了该工作面外侧相邻矿井的采空区积水边界,为矿井防治水提供了依据。Ascertaining goaf water boundary in coal mine, can effectively prevent the occurrence ofwater damage accidents.By using the mine transient electromagnetic detection technology, the sameinstrument was used to detect the known area in the underground field of Yechuan coal mine, and theelectrical law of the transient electromagnetic in the mine was obtained, then the outside of the returnairway of 3103 working face of Yechuan coal mine, the boundary of the goaf of the goaf adjacent to theoutside of the working face is delineated, which provides the basis for the prevention and control.
