摘要
圈定含水层的富水区范围、推断富水性强弱是煤矿地球物理勘探的研究重点之一。TEM具有对低阻体反映灵敏的优势,是解决矿井水文地质问题较为理想的探测手段。在资料处理过程中尝试利用测井资料标定层位,解释过程中利用岩性分析、砂泥岩比值参数,依据物探低阻异常区综合推断富水区范围及富水性强弱。实例表明,效果良好。
One of the research focus of geophysical exploration in coal mine is how to delineate the range of water and infer the water abundant area. TEM is a ideal detection method to solute the hydrogeological problems of mine and has the advantage of reflecting the low resistivity body sensitively. In this paper, we use logging data to de-marcate horizon, to infer comprehensively the water abundance and the range of water abundant area according to the geophysical low resistance anomaly together with the lithology analysis and sand shale ratio parameters in the interpretation process. Examples show that the results are good.
