金川不良岩体巷道支护技术可行性研究
|
摘要
金川不良岩体中巷道支护一直是困扰矿山生产的重大难题。由于矿区特殊的地质构造 ,形成很大的地质构造应力 ,岩体结构发育 ,巷道支护相当困难。借助于FLAC有限差分软件 ,进行模拟分析和方案优选 ,调整支护强度及刚度 ,限制围岩变形 ,以达到支护稳定的目的
Tunnel supporting in harmful rock is a very difficult question, which feazes JinChuan mining production Due to mining field especial geologic structure, there is a great tectonic crustal stress, resulting in rock structure upgrowth Basing on present supporting status analysis and recurring to FLAC finite difference analysis software, this paper puts up simulate analysis and supporting scheme optimize selection By means of adjusting supporting intension and stiffness, confining wall rock distortion and arriving at intention of supporting stab ilization.
