摘要
围岩松软、呈层性显著以及受爆破震动和开采动载的反复作用是回采巷道的基本特征。在对这些基本特征分析的基础上,提出了回采巷道锚杆支护设计的一些基本原则。
Soft and thin-bedded characteristics and dynamic load action from mining and blasting shock are some basic features of the actual mining roadways in coalmine.Based on the analyses of the basic features,some basic bolting design criteria of the actual mining roadways in coalmine are put forward.
