摘　　要：黄土塬区地形地质条件复杂,运用瞬变电磁法开展矿井水探测能取得较好效果。在试验基础上,获取了测区大定源回线装置最佳发射框尺寸、发射频率及供电电流等参数,并将其运用于有效性试验,获得了区内视电阻率分布特征。实验区视电阻率三维切片图表明:煤系地层中不连续分布的低阻异常,推断为巷道分布位置;由于顶板冒落,裂隙可能导通上部砂岩含水层,建议开采前采取有效的探放水措施。The topographic and geologic conditions of Loess Plateau areas are complex, using transient electro- magnetic method （TEM） to detect roadway water abundance can get better results. Based on parameter experi- ments, the optimal emitter loop size, frequency and supply currents have been obtained. Using these parameters in efficiency assay, the rules of apparent resistivity distribution have apparent resistivity were drawn. The results showed that the low ers were the roadway. Because of the roof tive water damage prevention measures are falling, fractures may recommended during been got, and then, three-dimensional sections of resistivity anomalies inside the high resistivity lay- conduct the upper sandstone aquifer. So the effec- the repeated mining.
