摘要
针对深部巷道复杂的应力环境和多变的围岩性质 ,对深部巷道围岩稳定性进行了分类预测、松动圈预测和数值计算分析 ,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 classification prediction, loosening ring prediction and numerical simulation according to the complex stress environment and the variable characteristics of surrounding rocks of deep roadway, which can be the 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.
