| 摘 要： | 随着煤矿的兼并重组以及资源整合，致使小煤矿采空区成为煤矿安全开采的突出隐患，为了对小煤矿采空区进行精确的探测，采用无损探测（综合物探）法，研究了瞬变电磁法、高密度电法等原理、然后分别采用三维地震综合法、高密度二维地震法、瞬变电磁法和高密度电法对该煤矿进行了探测，研究得出，二维探测结果和三维综合探测结果，在空间上异常区域具有较高的吻合关系，然后根据该异常区域，在地面圈定了7个验证孔的坐标，由验证孔的工程勘探，验证了该煤矿采空区的位置以及形成采空区的原由，表明了综合物探法对煤矿采空区的探测是可行的、有效的，研究为同地质条件下小煤矿采空区的探测提供了技术支持。

| Abstract: | With the merger and reorganization of coal mines and the integration of resources，the mined-out area of small coal mines has become a prominent hidden danger in the safe mining of coal mines.In order to detect the mined-out area of small coal mines accurately，the principles of transient electromagnetic method and high-density electrical method were studied by using comprehensive geophysical prospecting method.Then three-dimensional seismic synthesis method，high-density two-dimensional seismic method，transient electromagnetic method and high-density electrical method were adopted respectively.The coal mine has carried on the exploration，the research obtained that the two-dimensional detection results and the three-dimensional comprehensive detection results with a high coincidence relationship in the spatial anomaly area，and then according to the anomaly area，the coordinates of seven verification holes were delineated on the ground.The engineering exploration of the verification holes verifies the location of the goaf and the reasons for the formation of the goaf in the coal mine，which indicated that the comprehensive geophysical prospecting method was applied to the coal mine.The detection of goaf was feasible and effective.The research provided technical support for the detection of goaf in small coal mines under the same geological conditions. |
