摘　　要：通过勘探实例,介绍了地面电法、三维地震等地面物探手段在采空区、断层及陷落柱探测中的应用,结合地质背景及煤矿采掘情况,对采空区积水、断层及陷落柱的含(导)水性进行了分析,多数解释成果得到了矿方验证,效果良好。根据当前煤炭资源勘查形势,地面物探技术应从煤矿安全生产需求出发,致力于煤矿隐蔽致灾地质因素的探测,注重加强在各种复杂地质条件下物探技术应用研究,将采空区积水、断层及陷落柱导水等精细探测技术作为物探技术的发展方向。Through prospecting cases, introduced surface geophysical prospecting means including surface electric method, 3D seismic prospecting etc. applied in gob area, fault and subsided column detection. Combined with geological setting and coalmine winning and opening carried out gob area ponding, fault and subsided column water-bearing （-conducting） property analyses. Majority of interpreted results have been verified by coalmine party with good effect. According to coal resource exploration status at present, surface geophysical prospecting technology should think over coalmine safety in production needs, devote to coalmine hidden geological hazard factors detection. Pay attention to strengthen geophysical prospecting applied research under various complicated geological conditions, taking the fine detection technology on gob area ponding, fault and subsided column water conduction as the geophysical prospecting technology development direction.
