摘要
分析了矿井瞬变电磁法在水害超前探测中的地质效果,并系统介绍了矿井瞬变电磁法探测的地球物理特征、基本原理、井下干扰特性,以及装置参数设计的选择原则。以峰峰矿区黄沙矿2106工作面运料巷探测为例,通过物探资料圈定的低阻异常区域经打钻验证,说明该物探方法的地质解释成果准确可靠,可为矿井防治水工作提供有效的技术支持。
This paper analyzed the geological effect of the mine transient electromagnetic method in the advance detection of water disaster and systematically described the geophysical characteristics, basic principle, underground interference features and the selection of parameter design of the mine transient electromagnetic method. By taking the detection of 2106 working face haulage gate in Huangsha Mine of Fengfeng Coal Mining Area as an example, the low- resistivity anomaly area which was delineated by the geophysical data and then verified by drilling indicated that the geological interpretation results of this geophysical prospecting method are accurate and reliable, and can provide an effective technical support for the prevention and control of the mine water disaster.
