电磁法技术在矿井工作面综合探测中的应用研究

Study on the application of electromagnetic technique in the comprehensive exploration of coal mine face

为防止工作面回采过程中发生突水事故,采用无线电波坑透和矿井瞬变电磁法综合探测技术,对招贤煤矿1302工作面进行构造及富水性的综合性探查,查明了工作面内构造及富水异常区,消除了工作面回采过程中的安全隐患,确保了工作面安全回采。结果表明,电磁法综合探测技术避免了单一物探方法探测的多解性,为煤矿安全生产提供了技术支撑。

In order to prevent water inrush accident in the process of working face mining,we used comprehensive detection technology,a method combining radio wave pit penetration and mine transient electromagnetic method,to explore the structure and water content of 1302 working face in Zhaoxian Coal Mine.We found out the structure and water-rich abnormal area in the working face,eliminating the potential safety hazard and ensuring the safe mining in the process of working face mining.The results show that the integrated electromagnetic detection technology can effectively avoid the multiple solutions detected by single geophysical method,and can effectively guide the safe producing.
