摘　　要：基于对瞬变电磁法和三维地震法这两种物探方法的勘测原理进行分析,结合现阶段煤矿防治水的实际状况,详细分析以上两种物探方法在煤矿防治水工作中的应用策略。分析认为,对采空区、煤层地质构造以及陷落柱等的勘测均可使用瞬变电磁法,但对于陷落柱的探测,采用三维地震法更为精准,因为陷落柱的形成大多是由于底层塌陷造成的,是一种胶结体,呈现出一种低密度、松散的结构特征。Based on the analysis of the survey principles of transient electromagnetic method and three-dimensional seismic method,combined with the actual situation of coal mine water prevention and control at present,the application strategies of the above two geophysical methods in coal mine water prevention and control work are analyzed in detail.The analysis shows that the transient electromagnetic method can be used for the survey of goaf,coal seam tectonics and collapse column,but the three-dimensional seismic method is more accurate for the detection of collapse column,because the collapse column is mostly formed due to the collapse of the bottom layer,which is a cement body,showing a low density and loose structural characteristics.
