摘　　要：自然电场法、充电法、对称四极激电测深法是常规的地球物理勘查方法,广泛用于采空区、地质灾害勘查及治理。尤其是对于地电条件复杂,地形切割剧烈,巷道不规范,采空区充水,测线不能按直线布设的工作区,而自然电场法、充电法的综合应用,则更显示了它的优越性,达到了较好的地质效果。本文结合工程实例,介绍综合物探用于采空区勘查的野外工作方法,通过分析采空区的地球物理特征,对综合物探资料解释,推断出采空区的平面位置及空间分布特征,为该采空区的危险性评估及治理提供了依据。经钻探验证,推断解释结果与实际地质情况吻合较好。The self-potential method, ＂mise-a-la masse＂ method and symmetric four--e- lectrode IP sounding method are the normal geophysical prospecting, which are widely used in goal prospecting and geological disasters＇ management. Especially in working area where geo-electricity is complex, topography incision is severe, tunnels are not standardized, goaf is full of water and survey line can not be placed straightly, Nevertheless, the self- potential method and ＂mise-a-la-masse＂ method perform better in those situations impro- ving the effectiveness of methods which leads to a good geological effect. This paper intro- duces how to apply complex geophysical prospecting methods to goal prospecting. By the way of analyzing geophysical characteristics of goal, it interprets the integrated geophysical
