矿井采空区突水防治方法研究

Study on goaf water prevention and control

为了解决整合矿井采空区突水危害问题,以河东煤田为研究背景,基于煤层赋存和水文地质开采条件,对矿井采空区的围岩破坏形式、保护煤柱的留设方法、采空积水的探放方式、采动过程中围岩的控制方法等方面进行综合分析,探讨矿井采空区突水的综合防治方法,解除采空区突水危害,为矿井的安全生产提供指导,对具有相同生产条件的矿井提供借鉴。

In order to solve the integrated mine goaf water problem, Hedong coalfield was taken as example, based on of coal seam occurrence and the hydrogeological exploration condition, the goaf surrounding rock broken type, coal column setting,goaf water discharge and surrounding rock control in mining were analyzed comprehensively, the gaof water prevention and control was discussed, which provided reference for safe mining to those mines with similar conditions.
