摘　　要：瞬变电磁探测技术在煤矿井下水害防治领域得到广泛应用,但井下现场金属干扰对瞬变电磁探测的不利影响无法避免,这给传统瞬变电磁超前探测技术的推广应用带来了挑战。为解决这一问题,基于瞬变电磁技术基本原理,研制了矿用钻孔瞬变电磁探测仪器,并开展了相关的现场应用试验。研究表明,该仪器具备探查钻孔径向隐伏水害异常的能力,利用井下钻孔开展施工,降低了矿井瞬变电磁技术对探测环境的要求,具有施工难度低、探测效率高的特点,能够满足工程应用的探测需求。Transient electromagnetic detection technology has been widely used in the field of water disaster prevention and control in underground coal mine,but the adverse effect of metal interference on transient electromagnetic detection is inevitable,which brings challenges to the promotion and application of traditional transient electromagnetic advanced detection technology.In order to solve this problem,based on the basic principle of transient electromagnetic technology,a set of mine borehole transient electromagnetic detection instrument was developed,and related field application tests were carried out.The research shows that the instrument has the ability to detect abnormal radial hidden water damage of borehole.By using underground borehole to carry out the construction,the requirements of mine transient electromagnetic technology on the detection environment are reduced.It has the characteristics of low construction difficulty and high detection efficiency,and can meet the detection needs of engineering applications.
