摘要: 在煤巷道穿越断裂施工时,往往选用经济高效的综合物探技术判别其富水性,但随着综合物探技术应用的推广,逐渐发现其勘探精度始终不高。结合山西古城煤矿煤巷道施工过程,开展综合物探技术实地研究,通过试验选择物探方法,并结合水化学同位素验证,清楚地揭示了煤矿巷道施工段富水性情况,弥补了综合物探勘探精度不高的缺陷。研究结果表明:选用综合物探技术并结合水化学同位素验证,在一定程度上能降低煤巷道施工建设中的隐患发生,对相同或类似情况煤巷道工程建设起到示范作用。Abstract: When the coal roadway crosses fracture construction, efficient integrated geophysical prospecting technology is often used to determine its water content. However, with the popularization of the integrated geophysical exploration technique, researchers have gradually found that its exploration precision is not high. In combination with the coal mine roadway construction in an ancient city of Shanxi, the authors selected the integrated geophysical prospecting method in combination with water chemical isotope verification and clearly revealed the hydrogeological condition of the coal roadway construction period, thus making up the defect of the integrated geo?physical exploration whose accuracy is not high. It is shown that integrated geophysical exploration technique in combination with water chemical isotope can greatly reduce the hidden dangers in the coal roadway construction. The results achieved by the authors provide a demonstration for the same or similar coal roadway engineering construction.
