摘要
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。
A study is made of the interaction between the face support and the surrounding rock, and interaction which exhibits rigidity equilibrium between the two. A relationship is established, upon this equilibrium, between the augment in the support resistance and the setting load towards a mining cycle end. Thereafter a discussion is given of the principles for determining rational setting loads under various geological conditions
