摘　　要：导水构造的超前预报是预防煤矿突水的关键,根据导水断层的致灾机理和地球物理响应特征,提出探测断层带位置和富水性的综合矿井物探技术:采用矿井地震反射波法探测断层的位置和形态,利用矿井瞬变电磁技术确定断层的富水情况,该方法组合兼顾构造位置及富水性的探测,克服了单一地球物理场勘探方法的局限性、降低其多解性.同时结合钻探技术,实现导(含)水断层的多方法、多参数综合精细探测技术.Advanced prediction of water conductive structures is the key of water-inrush prevention in coat mines. Base on the geophysical characteristics of water-bearing faults, theintegrated mining geophysical method for the location and water-bearing properties of faults is expounded： seismic reflection method is used to determine the location of the fault, meanwhile the water-bearing properties of the fault is determined by the transit electromagnetic technology. In comparison, integrated mining geophysical technology can overcame the limitations of single geophysical method and reduce the multiplicity. Combine with the drilling achievement, an efficient and accurate prospect of faults is realized, using multi-method and multi-parameter.
