矿井瞬变电磁原始数据质量提升措施研究

Study on Measures to Improve the Quality of Mine Transient Electromagnetic Raw Data

为了提高矿井瞬变电磁法原始数据质量,需要对现场探测的干扰因素进行全面研究。在经过对迎头超前探测和工作面探测两种不同探测方式下,不同人文干扰体的干扰程度充分研究后,开发出数据质量检测软件,结合内蒙某矿的回风顺槽数据的进行检测试验,定位干扰存在位置,随后进行回访排查和干扰剔除处理,最终实现矿井瞬变电磁原始数据质量提升的目标。

In order to improve the original data quality of mine transient electromagnetic method,it is necessary to comprehensively study the interference factors of field detection.After fully studying the interference degree of different human interference bodies under the two different detection methods of head-on advance detection and working face detection,the data quality detection software is developed.Combined with the detection test of the return air chute data of a mine in Inner Mongolia,the interference location is located,and then the return visit and interference elimination processing are carried out,so as to finally achieve the goal of improving the quality of the original data of mine transient electromagnetic.
