煤矿开采过程中需探明矿井隐含的水害风险,以保证矿井的安全生产工作.为解决宝英煤矿老窑积水、采空区积水、断层与陷落柱较为发育而难以探明的问题,采用并行直流电法、音频电透视法、瞬变电磁法对+1 233 m水平西运输巷底板与+1 233 m水平西辅助进风巷进行综合物探分析.在分析不同物探技术原理上,对施工参数进行了设计,并对数据进行反演分析,综合对比3种物探技术的探测成果.结果表明,探测区域主要存在4种类型的地质与水害威胁:隐伏构造导致的地层裂隙高度发育并富含裂隙水;+1 233 m水平西辅助进风巷揭露断层;+1 233 m水平西辅助进风巷靠近陷落柱富水区域;底板老窑积水以及底板水渗透导致的异常区域.综合物探结果为宝英煤矿水害问题的探测与防治提供了指导.
Detection and analysis of integrated geophysical exploration technology in the prevention and control of mine water damage in Baoying Coal Mine
In the process of coal mining,it is necessary to find out the hidden risk of water damage in the mine to ensure the safe pro-duction of the mine.In order to solve the problems that the accumulation of water in the old kiln,the accumulation of water in the goaf,the fault and the collapse column are relatively developed and difficult to discover,the parallel direct current method,audio frequency electrofluoroscopy and transient electromagnetic method were used to conduct comprehensive geophysical analysis on the floor of+1 233 m horizontal west transport roadway and+1 233 m horizontal west auxiliary air inlet roadway.On the basis of explaining the principle of different geophysical exploration techniques,the construction parameters were designed,the data were analyzed by inversion,and the detection results of the three geophysical exploration techniques were synthetically compared.The results show that there are four types of geological and water hazards in the detection area:strata fractures caused by hidden structures are highly developed and rich in frac-ture water;+1 233 m horizontal west auxiliary air inlet roadway to expose the fault;+1 233 m horizontal west auxiliary air inlet road-way is close to the water-rich area of the collapse column;abnormal areas caused by the water in the old kiln of the floor and the water infiltration of the floor.The comprehensive geophysical exploration results provide guidance for the detection and control of water damage in Baoying Coal Mine.
