摘要

本文以西铭矿南四上车场巷道围岩为研究对象,利用孔内电视探明巷道围岩破碎状态并圈定围岩破碎范围,提出以岩体破碎深度为依据的支护方式,通过数值模拟手段对现有和优化后的支护方案进行了对比分析,研究表明,考虑岩体破碎深度的精准定位支护方式可以更有效控制岩体变形,提供围岩稳定性,保证矿山安全、高效生产。
        In this paper, the surrounding rock of the roadway in the South Fourth Railway Yard of Ximing Mine is taken as the research object. The broken state of the surrounding rock of the roadway is identified by the borehole TV and the surrounding rock fragmentation range is delineated and the support method based on the fracture depth of the rock mass is proposed. By means of numerical simulation, the existing and optimized support schemes are compared and analyzed. The results show that the precise positioning support method considering the depth of rock fragmentation can control the deformation of rock mass more effectively, improve the stability of surrounding rock, and ensure the safe and efficient production of mines.
