摘　　要：基于对矿井瞬变电磁法和高密度电阻率法理论基础、技术特点及其方法局限性的分析,提出综合运用两种方法进行工作面水文地质条件探测,结合某矿121101工作面水文地质条件探测实例,探讨综合地球物理探测的工作方法技术、数据采集方法、资料处理与解释方法等。工程应用结果表明:综合地球物理探测方法,既可以弥补矿井瞬变电磁法无法分辨顶、底板异常响应的缺陷,又可以对两种方法的探测结果相互验证,排除由于扰引起的假异常,从而有效查明矿井工作面开采水文地质条件,为工作面安全回采提供技术保障。Based on the analysis of theoretical basis,technical characteristics and limitations of mine transient electromagnetic method（MTEM） and high density resistivity method,this paper proposed the integrated geophysical method to detect hydrogeological condition of mine working face by combining the above two methods.With the detection case in 121101 working face,this paper discussed the working procedure,data acquisition,processing and interpretation methods of integrated geophysical detection.Results of engineering application show that the integrated geophysical method can remedy the defect of mine transient electromagnetic method （unable to distinguish the abnormal responses of roof and floor） and contrast the detecting results of both methods,thus remove the false anomaly aroused by interference.The integrated geophysical method can effectively detect the hydrogeological condition of mine working face and provide technical support for safe mining.
