摘要
瞬变电磁法对地下水反应敏感,而矿井瞬变电磁法具备距离目标体近,分辨率高的特点。为此使用福州华虹智能科技开发有限公司研发生产的YCS40(A)瞬变探测仪,采用重叠回线装置布置线圈,对贵州盘江精煤股份有限公司月亮田矿1118117工作面顶板赋水性进行了探查,指出1118117工作面回风巷顶板以上至100米高度的范围内(0～180m段),受1118115工作面采动影响,顶板含水裂隙发育,巷道顶部存在富水异常区,并得到了钻孔探放水施工验证,为工作面安全回采提供了可靠的技术支持。井下探放水和工作面回采资料表明,瞬变电磁法探测工作面顶板赋水性具有较高的准确性。
Transient electromagnetic method to groundwater and sensitive response, mine transient electromagnetic method with distance from the target object, high resolution. Therefore the use of Fuzhou Huahong intelligent science and technology development limited company R ＆ D and production of YCS40 （ A ） transient detector, using overlapping loop coils are arranged, on Guizhou Panjiang Coal Company Limited of Yueliangtian mine 1118117working face roof water bearing undertook exploration, out of lllSll7working face air return way above the top plate to the 100 m high range （0 ~180m ）, by the 1118115working face min- ing influence, roof aqueous fractured, top of the tunnel in water rich anomaly area, and the drilling exploration and drainage con- struction test, for the working face mining safety provides reliable technical support. Drilling flak and mining data show, transient electromagnetic method for detecting water bearing roof of working face with high accuracy.
