摘要
针对深部巷道复杂的应力环境和多变的围岩性质 ,对深部巷道围岩的稳定特征进行了数值模拟分析 ,为深部巷道锚杆支护提供了理论依据 ,并对锚杆支护参数进行了优化设计 。
The stability of surrounding rocks is analyzed by the method of numerical simulation according to the complex stress environment and the variable characteristics of surrounding rocks of deep roadway, which can be theory basis for bolting of the deep roadway The support parameters of bolting are also designed optimally in this paper All these ensure the optimization of the bolting and the stability of deep roadway in the long run
