矿井采掘巷道中高强支护方案的应用分析

Application of High-strength Support Solutions in Mine Rxcavation Tunnels

针对矿井采掘作业中,巷道不稳定顶底板及围岩易出现严重变形的问题,为有效控制矿井巷道顶底板及围岩变形量,更好地保障矿井安全生产,结合某矿井巷道工程概况,介绍了该矿井巷道原支护方案,分析了其存在的不足,并提出了一些改进优化措施。实际应用结果表明,通过综合应用这些改进优化措施后,巷道的顶底板及围岩变形量明显减小,达到了安全范围内,保障了矿井安全生产,取得了较好的支护效果。

In order to effectively control the deformation of the top and bottom plates and the surrounding rocks in the mine tunnel, and to better ensure the safe production of the mine, the original support scheme of the mine tunnel was introduced, its shortcomings were analyzed, and some improvement and optimization measures were proposed. The practical application results show that, through the comprehensive application of these improvement and optimisation measures, the deformation of the top and bottom slab of the roadway machine surrounding rock is significantly reduced and reaches the safe range, which guarantees the safe production of the mine and achieves a better support effect.
