本文通过对支架与围岩相互作用机理的研究,依支架与围岩平衡刚度建立了循环末阻力增量与初撑力的关系。讨论了针对不同地质条件,合理初撑力的确定
Based on the study of the interaction mechanism between support and surrounding rock, this paper establishes the relation between the increment of end-of-cycle resistance and initial support force according to the equilibrium stiffness of support and surrounding rock. Discussed for different geological conditions, the determination of reasonable initial support
