摘要
长期以来,煤矿水害给国家和人民带来的经济损失和人身伤亡极为惨重,严重威胁着煤矿的安全生产,许多矿井在实际建井生产中发现水文地质条件较复杂,井下发生多次在巷道掘进中冒顶突水事故,给井下施工带来很大困难。因此在煤矿开采前需探明煤层顶底板砂岩的富含水性。本文以潞安常村煤矿电法勘探为例介绍了如何利用瞬变电磁法探测煤层顶底板砂岩水,并且在资料解释处理过程中采用了特殊处理方法,该方法已在晋城、朔州、潞安各矿等多个矿区进行了运用,部分资料成果在煤矿生产过程中已得到验证,准确率相对较高,充分说明了瞬变电磁法在探测煤层顶底板水方面起到的重要作用。
For a long time,Mine water hazard to the country and the people of the economic losses and human casualties very heavy,Serious threat to the safety of coal production, Many mines in the actual construction of wells in production of more complicated hydrogeological conditions found, Mine occurred several times in the roadway excavation cave-water inrush, Caused great difficulties for underground construction. In this paper, Luan Coal Mine usually electrical prospecting for example, Describes how to use the transient electromagnetic method to detect water sandstone coal seams,and explain the process in the data used in a special treatment,the method has been in Jincheng. Shuozhou.Luan mining the ore. and other were used,Some of the information production process results in a coal mine has been verified,relatively high accuracy. TEM fully illustrated exploration of coal seams in the water play an important role.
