瞬变电磁法（简称TEM），属于感应类电磁探测方法。由于该方法探测深度大，对低阻体敏感，地形适应性强，且在野外施工效率高等诸多优点而得到广泛应用，目前已成为煤矿水害探测最为有效的方法之一,为矿井防治水措施的制定提供科学依据。 论文首先对煤矿水害探测的现状进行了分析，阐明了TEM在煤矿水害探测中的重要性；然后从麦克斯韦方程出发，对TEM的参数设置、装置选择、地形影响、数据处理与解译等关键技术进行了研究；最后论文在两个煤矿的瞬变电磁探测的实际应用，以采空区积水和含水层特征为基础，结合不同地方、不同环境、不同施工条件和不同施工要求等，选择了合理的工作装置及有效的工作参数，对施工中的干扰采取了合理方法进行压制，选取合理的正演模型作为初始参数进行了反演。大南湖一矿和豹子沟煤矿探测研究成果经矿方实际验证，证明了瞬变电磁法在煤矿水害探测应用中的有效性。 论文研究认为瞬变电磁在煤矿水害探测中应用效果良好，可以为矿井防治水工作更好服务。本文研究成果，为瞬变电磁法的应用、推广起到一定的借鉴作用。

Transient electromagnetic method (TEM), as part of the induction electromagnetic detection method. Due to detecting depth is big, this method is sensitive to the low resistance body, terrain adaptability is strong, and higher efficiency in the field of many advantages and is widely used, has now become one of the most effective method for detection of coal mine water hazards were also, to provide scientific basis for the establishment of mine water prevention and control measures. Paper first analyzes the detection of the current situation of coal mine water hazards were also, puts out the importance of the coal mine water hazards in TEM in detecting; Then starting from maxwell's equation, parameter setting of TEM, device selection, terrain effects, the key technology such as data processing and interpretation are studied; The final papers in two practical application of transient electromagnetic exploration of coal mine, on the basis of goaf water and aquifer characteristics, combined with different places, different environment, different construction conditions and construction requirements, etc., choose the reasonable work system and effective working parameters, the construction of interference suppression, the reasonable methods for the selection of reasonable forward model as the initial parameters for the inversion. Large south lake a mine and the leopard ditch coal mine exploration research results verified by actual ore party, proved that the transient electromagnetic method in detection of the application of coal mine water hazards were also effective. In this paper, we study that transient electromagnetic coal mine water hazards in the exploration of application effect is good, can better service for mine water prevention and control work. This article research results, for the application of transient electromagnetic method, the promotion play a certain reference function.
