工作面全方位瞬变电磁探测水害技术应用

Application of omnidirectional transient electromagnetic detection of water hazard in working face

汾西矿务局水峪煤矿全面引进矿井瞬变电磁技术,利用瞬变电磁技术的非接触探测与可灵活控制探测方向的技术优点,并对施工现场进行严格把控,克服其技术缺点,总结和积累了大量现场应用经验,形成了一套行之有效的工作面全方位探测技术方案,攻克了工作面内顶底板水害异常体难以精确探查的技术难题。水峪煤矿严格按照《煤矿防治水细则》和矿务局防治水文件要求,采用自主总结形成的工作面全方位探测技术方案开展物探工作,能有效、可靠地为水峪煤矿的防治水工作提供技术指导。

Shuiyu Coal Mine of Fenxi Mining Bureau began to fully introduce the transient electromagnetic technology of the mine.By using the advantages of non-contact detection of transient electromagnetic technology and flexible control of detection direction,the construction site is strictly controlled to overcome its technical shortcomings.Through summarizing and accumulating a large number of field application experience,a set of effective omni-directional detection technology scheme for working face has been formed,and has overcome the technical problem that it is difficult to accurately detect the abnormal body of water disaster in the roof and floor of the working face.At present,Shuiyu Coal Mine strictly follows the"Water Regulations for the Prevention and Control of Coal Mines"and the requirements for water prevention and control documents of the mining bureau,and adopts the comprehensive detection technology scheme formed by the independent summary to carry out geophysical exploration work,these measures can effectively and reliably provide technical guidance for water prevention and control in Shuiyu Coal Mine.
