受动压影响巷道锚杆支护优化方法

Optimum Design of Bolt Support Method for Dynamic Pressure Roadway

针对目前巷道锚杆支护及对于锚杆受力研究不足而导致的成本过高等问题,对采动巷道锚杆支护机理进行了分析,阐述了动压巷道锚杆受力情况以及围岩变形情况,在保证安全的情况下对锚杆支护的参数进行了优化设计,实现低成本下的支护最优化。

In order to solve the problem such as the insuffcient roadway bolt support, the high cost of the bolt, in the paper the mechanism of bolt support, in which the stress of the bolt in the dynamic roadway and the deformation of the surrounding rock are expounded, and the parameters of the bolt support are optimized under the condition of ensuring the safety.realizing the optimization of the support under the low cost.
