摘要: 以魏墙煤矿二盘区回风大巷延伸掘进区为研究对象,通过对矿井地质、水文地质条件进行分析,结合前期采用物探、钻探等手段对老空区探查,确定巷道掘进的主要充水威胁,而后在大巷掘进过程中进行超前钻探、水化学分析,最终保证巷道完成安全掘进。结果表明:矿井二盘区大巷掘进前期,通过地面三维地震、瞬变电磁法勘探,圈定了若干疑似老空异常区和富水区,通过钻探工程、电视测井等对老空区进行验证,发现在井田二盘区南部边界存在老空区及积水区。根据圈定范围设计巷道布局,结合物探成果,在最南侧的回风大巷掘进阶段进行井下超前钻探,同时对钻孔异常出水进行取样测试分析,发现所探查区域未见老空区。Abstract: The extended tunneling area of the return-air roadway in the second mining area of Weiqiang Coal Mine was taken as the research object. Through the analysis of mine geological and hydrogeological conditions, combined with the previous exploration of goaf by means of geophysical exploration and drilling, the main water-filling threat of roadway tunneling was determined. Then, in the process of roadway tunneling, advanced drilling and hydro-chemical analysis were carried out to ensure the safety of roadway tunneling. The results show that: in the early stage of roadway tunneling in the second mining area of the mine, a number of suspected goaf abnormal areas and rich water area were delineated by surface 3D seismic and transient electromagnetic exploration. Through the verification of the goaf area by drilling engineering and TV logging, it is found that there are goaf and water areas in the south boundary of the second mining area of the coal field. According to the delineation range, the roadway layout was designed. Combined with the geophysical exploration results, advanced drilling was carried out in the underground during the heading stage of the return-air roadway on the southernmost side. At the same time, the abnormal water from the borehole was sampled and analyzed, and it was found that there was no goaf in the explored area.
