摘要
为了提升煤矿井下瞬变电磁测量数据的可靠率,通过调查找到目前探测存在的主要问题,从多个角度分析了其影响因素,认为测量人员专业素质、现场操作测点重复测量控制、背景电磁噪声、金属、积水干扰为瞬变电磁测量可靠性低的主要原因,从而提出了可靠率提升技术措施。通过现场试验分析可知,采取措施后瞬变电磁测量可靠性提升了15%。
In order to improve the reliability of transient electromagnetic measurement data in coal mine, the main problems existing in detection are found through investigation, and the influencing factors are analyzed from many angles. It is considered that the professional quality of surveyors, repeated measurement control of on-site operating measuring points, background electromagnetic noise, metal and stagnant water interference are the main reasons for the low reliability of transient electromagnetic measurement, and the technical measures to improve the reliability are put forward. Through the analysis of the field test, we can see that the reliability of transient electromagnetic measurement has been improved by 15% after taking measures.
