摘　　要：滋阳断层穿越东滩煤矿矿井边界,为水的赋存与运移提供了可能,对矿井生产安全构成潜在威胁。为消除安全隐患,使用对低阻异常敏感的瞬变电磁法探测采掘范围内的断层导水带分布情况,以进行针对性的排放治理,采用电性源瞬变电磁法,利用接地线源,有效规避研究区内地表存在的诸多人文建筑和交通线路,减少地形影响。研究结果表明,电性源瞬变电磁法可以准确地分辨低阻薄层,为煤矿采区和采面设计提供可靠依据,从而提高矿井安全生产水平。The Ziyang fault crosses the mine boundary of Dongtan Coal Mine,providing the possibility for the occurrence and migration of water,posing a potential threat to the safety of mine production.To eliminate safety hazards,the transient electromagnetic method sensitive to low resistance anomalies is used to detect the distribution situtaion of fault water conducting zones within the mining and excavation range,so as to carry out targeted emission governance.The electrical source transient electromagnetic method is adopted,and the grounding wire source is used to effectively avoid the presence of many cultural buildings and transportation lines on the ground surface of the study area,reducing the influence of terrain.The research results indicate that the electrical source transient electromagnetic method can accurately distinguish low resistance thin layers,provide reliable basis for coal mine mining area and mining face design,and thus improve the level of mine safety production.
