摘要:
岩体稳定性评价是巷道开挖和支护设计时的一项基本任务。本文基于岩体质量分类方法，通过对塔尔德布拉克左岸金矿的工程地质调查，结合矿岩物理力学参数，对矿石和围岩进行了稳定性分级，并根据矿岩稳定性分级提出了针对性支护方案，并取得了较好支护效果。
Stability evaluation of rock masses is a basic procedure for the design of various underground excavations and support measures. In this paper, engineering geological investigation into country rock and ore body around excavations was extensively carried out; and samples were collected to test their physic-mechanical parameters in laboratory. Then, engineering rock masses in question were classified based on rock mass rating (RMR) and accordingly ground support measures were also proposed with a good effect obtained.
