摘　　要：基于矿井瞬变电磁法理论以及技术应用,采用非接触式、多匝重叠回线装置探测断层赋水性,并在安徽刘桥一矿进行了实例应用。结合实际地质资料对比表明,当煤岩层中存在断层、陷落柱的含水构造,矿井瞬变电磁法能够准确的监测断层构造赋水性,为矿井安全生产提供可靠依据。Ascertaining the hydro-geological conditions in the working face and coal seam ad- jacent to the mine is an extremely important activity in order to ensure safe production. Based on the whole-space transient electromagnetic method and application technology, this paper adopts a non-contact and multiple circle number overlapping back line device to explore the water content in faults. This has been applied at Liuqiaoyi coal mine in Anhui. Comparing the actual geological data, the authors ascertained that when water-bearing structure such as faults and collapse columns exist in coal seams, mine transient electromagnetic methods can be utilized to accurately detect the water content in the fault structures and provide a reliable basis for safe production.
