分析了采场支架与围岩系统的组成及其铡度，得出了在支架与围岩系统中，当直接顶与支架的相对刚度不同时，支架可具有不同的工作状态，并提出了支架在不同工作状态下适应围岩运动状况所应具有的基本条件。
The composition and the degree of stope and surrounding rock system are analyzed. It is concluded that the support can have different working status when the relative stiffness between the direct roof and the support is different in the support and the surrounding rock system, and the support Under different working conditions to adapt to the basic conditions of the surrounding rock movement should have.
