天然电场选频法在某铜矿注浆工程中的应用

Application of Natural Electric Field Frequency Selection Method in the Grouting Engineering of a Certain Copper Mine

结合城门山铜矿二期帷幕工程,采用天然电场选频法对地下水过水通道进行探查,并通过注浆试验孔的压水试验加以验证,物探成果与压水试验成果吻合度较高。实践证明天然电场选频法在地下水动力条件下查找地下水过水通道具有很强的实用性,对岩溶地区注浆帷幕工程的设计与施工有较高的指导和借鉴作用。

According to Phase II grouting curtain engineering of Chengmenshan copper mine, natural electric field frequency selection method is adopted to investigate underground water channel, water pressure test is used for grouting drill hole to verify that geophysical exploration result is highly matched with result of water pressure test. It proves in practice that natural electric field frequency selection method has strong practicability in finding underground water channel under the condition of underground water power, and it has high practical and reference value in design and construction of grouting curtain engineering in Karst area.
