摘要
针对石泉煤矿30107工作面胶带顺槽揭露的X5陷落柱,开展详尽的钻探勘查工作,深入探查X5陷落柱内部结构、密实程度、含导水特性以及精确的边界范围,通过运用钻孔电视和钻孔地质雷达等先进探测技术,对陷落柱柱体结构的完整性特征进行细致研究,揭示陷落柱形成过程中的变化规律及其当前的赋存状态,使用高密度电阻率法和大地电磁法等一系列综合手段,最大限度地保证矿井生产活动的安全性。试验结果对X5陷落柱及其附近区域的水文条件和地质条件进行了探查,对研究陷落柱的稳定性、后续指导受奥灰承压水威胁的3号煤层开采防治水工作、确保安全带压开采提供了重要的地质依据。

Abstract
A detailed drilling and exploration work is carried out on the X5 collapse column exposed by the 30107 working face tape groove in Shiquan Coal Mine. The internal structure, compaction degree, water conducting containing characteristics, and precise boundary range of the X5 collapse column are thoroughly investigated. Through using advanced detection technologies such as borehole TV, borehole geological radar and so on to study the integrity characteristics of the column body structure of collapse column in detail, revealing the changes law in the formation process of the collapse column and its current occurrence state. A series of comprehensive means such as high-density resistivity method, magnetotelluric method and others are used to maximize ensure the safety of mine production activities. The experimental results explore the hydrological condition and geological condition of the X5 collapse column and its nearby area, providing important geological basis for studying the stability of the collapse column, follow-up guiding the mining and water prevention and control work of the No.3 coal seam threated by Ordovician limestone confined water, and ensuring safe mining with pressure.
