摘要
为了解决煤矿井下支护依靠人工经验,安全性差的不足,利用应力实际监测、仿真分析的方案对某煤矿井下地质应力分布特性进行了研究。结果表明随之巷道深度的增加,煤矿井下的水平应力场逐渐降低,而垂直应力场会逐渐增加,而且采动应力随着距离综采面的增加会逐步降低,通过综合运用预应力锚固技术、注浆加固技术等,能够有效提升巷道围岩的稳定性。
In order to solve the problem that underground support in coal mine depends on manual experience and has poor safety,the distribution characteristics of underground geological stress in coal mine are studied by using the scheme of actual stress monitoring and simulation analysis.The results show that with the increase of the roadway depth,the horizontal stress field in the coal mine will gradually decrease,while the vertical stress field will gradually increase,and the mining stress will gradually decrease with the increase of the distance from the fully mechanized mining face.The stability of the surrounding rock of the roadway can be effectively improved through the comprehensive application of prestressed anchorage technology,grouting reinforcement technology,etc.
