摘要
煤矿开采中最重要的地质任务是探测采区内小构造的分布及其含(导)水性,采区三维地震勘探主要用于探测地质构造,而电法勘探则用于含水构造的探测.本文结合实例介绍了应用瞬变电磁法并结合三维地震进行煤矿采区水文勘探的基本原理、野外施工技术及资料处理解释方法.实际应用表明,瞬变电磁法与地震勘探的综合水文勘探降低了物探资料多解性问题,大大提高了勘探精度,可为煤矿防治水工作提供可靠的水文地质资料.
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.
