摘　　要：针对矿井电磁技术在煤矿安全保障领域的应用现状,例举了矿井直流电法、矿井瞬变电磁法、矿井无线电波坑道透视法等技术在井下所使用的仪器、装置形式、工作参数、工作环境及能够解决的地质问题与探测精度,指出矿井电磁勘探技术在探明巷道前方与及工作面两侧与顶底板内的含导水构造、断层、破碎带、岩溶、积水采空区等方面具有独特优势,特别是对呈低阻异常的富水范围的圈定,其准确率较高。In allusion to application status quo of mine electromagnetic technique in coalmine security domain, listed underground instrument, installation forming, operation parameters, operation environment, geological issues can be solved and detection accuracy of mine direct current, transient electromagnetic, underground radio wave penetration methods and techniques, pointed out the unique predominance of mine electromagnetic technique in detection of water hearing and conducting structures, fault, fracture zone, karst, water filled gob area in roadway front and both sides of working face and in roof and floor. Especially can circle out water-rich regions show themselves conductive anomaly with rather high accuracy.
