小构造及其贯通的探测在煤矿地质中占有重要地位。三维地震法主要用于探测地质构造，而电法主要用于探测充水构造。本文结合实例介绍了该方法的原理、野外工作流程、资料处理和解释方法。将瞬变电磁法与三维地震相结合的方法应用于矿区水文地质勘察。结果表明，瞬变电磁法与地震法相结合，在一定程度上解决了多解性问题，提高了探测精度，为煤矿水害防治提供了可靠的水文地球物理信息。
Exploration of small structures and their transmissivity is very important in coal mining geology. the 3D seismic method is mainly applied in detecting geological structures while the electrical method is mainly applied in detecting structures which are filled with water. In this paper according to some examples, the principle, the field procedure, the method of data processing and interpretation are introduced. The TEM combining with 3D seismic method is applied in hydrogeological prospecting of mining district. The result indicates that the combination of TEM and seismic method can solve, to some extent, the problem of multi-solution, improve the detecting precision, and provide reliable hydro-geophysical information for the prevention and control of water disaster in coal mines.
