| 近年来，采空区塌陷事故频发，采空区勘查重要性越来越高，为了更有效的开展采空区勘查工作，在胶东某金矿开展了采空区勘查试验，探索多物探方法在采空区勘查中的应用效果。在严重干扰条件下的矿区内开展了瞬变电磁法的多种装置类型、直流高密度电阻率法及浅层地震等多种物探方法选择试验。最终选择了高密度电法及等值反磁通瞬变电磁法进行了试验剖面。根据钻孔工程验证，证明了两种方法的有效性，同时对采空区充水条件的分析，使得推断结果更合理准确，对采空区勘查总结了一些经验。 |

| In recent years, collapse accidents often occur in worked-out areas of mines, indicating great importance of exploration to these areas. This paper presents an application of multi-geophysical methods in the exploration of the worked-out area in a gold mine of the Jiaodong region. Under the condition of serious disturbance within the mining area, transient electromagnetic survey with many device types, dc high density resistivity measurement and shallow seismic exploration were conducted successively as choice experiments. Finally the high density resistivity method and the equivalent inverse flux transient electromagnetic method（OCTEM） were chosen in the test section. Drilling verification shows the effectiveness of the two methods, and the analysis on the water filling condition made the inference conclusions from the survey more reasonable and accurate. |
