恩洪矿区水害事故分析及防治对策

Analysis of Water Disasters and Control Countermeasures in Enhong Mining Area

为了进一步研究恩洪矿区近距离煤层群开采过程中的水害防治问题,通过对矿区水文地质条件和矿区内典型透水事故的分析,认为恩洪矿区近距离煤层群上部煤层开采后造成大量的采空区水体位于现开采煤层上方,采空区水为矿区主要的水害威胁。随着煤炭资源整合的不断深入,矿区内有近1/3的煤矿需要关闭而形成新的废弃矿井和采空区,整合后矿井的水害防治问题也将日益显现,区内煤矿防治水技术能力不足以应对当前存在的水害防治现实问题。在分析的基础上,提出了恩洪矿区今后水害治理工作的对策措施。

In order to further investigate the prevention and control of water disasters in the mining process of the closed distance coal seam group in Enhong mining area, by analyzing the several typical water inrush accidents and the hydrogeological conditions of the mining area, it obtained that a lot of goal water located above coal seam, which was caused by the upper coal seam mining of the closed distance coal seam group in Enhong mining area, and the goal water was the main threat to water disasters. With the deepening of the coal resources integration, there were nearly one third of coal mines which needed to be closed and formed the new abandoned mines and coal mine goal. The problem of the prevention and control of water disasters became increasingly apparent after the mine integra- tion, water prevention and control technology was not enough to deal with the current prevention and control of water disasters reality problems in coal mines of this area. On the basis of the analysis, it put forward the countermeasures of water disasters control work for the Enhong mining area in future.
