摘要
针对煤矿井下巷道预应力锚索支护技术的应用实践进行了分析探讨。对预应力锚索在西曲矿特大断面开切眼、强烈采动影响巷道的案例进行了实践应用的分析,提出了存在的问题,并提出了相应的改进建议。实践应用效果表明,预应力锚索支护技术能有效控制煤矿井下巷道围岩的变形量,支护效果理想,为实现西曲矿高产高效安全的开采目标奠定了基础。
The application of prestressed anchor cable support tech nology in coal mine underground roadway is analyzed and discussed.This paper analyzes the practice application of prestressed anchor cable in the large section of Xiqu mine,and puts forward some suggestions for improvement.The practical application results show that the prestressed anchor cable support technology can effectively control the deformation of surrounding rock in coal mine underground roadway,and the supporting effect is ideal,which lays a foundation for realizing the mining goal of high yield,high efficiency and safety in Xiqu Mine.
