摘要
本文通过井下试验,研究了工业游散电流、浮煤、铁轨、金属支架等非地质因素对矿井电测结果的影响规律,在此基础上提出了避开和压制地电干忧、表层电性不均匀体等非地质因素影响的方法技术.几年的井下工作实践表明,文中所述方法有效、可行.同时,本文提出的方法对于矿区地面电法同样适用.
This paper makes an underground experimental study of the law of influence of various non-geological factors such as industrial stray current, float coal, iron rail and metal frame etc to the result of electrical testings in mine shaft, on the basis it presents the methods and technology to avoid and restrain the influence of non-geological factors such as interference of ground current nonuniformity of the efectric properties of superficial layers etc. Practice of several years of underground shaft works manifests that the methods stated in this paper are effective and feasible. At the same time the methods presented herein are equally applicable to surface electrical prospecting method at the mine areas.
