支架初撑力与上覆岩层运动作用机理

Action between setting load of supportmechanism of face upper strata movement

本文在分析支架初撑力与整个采场上覆岩层因自重运动作用机理的基础上，解决了控制采场上覆岩层运动所应具备支架合理初撑力的确定问题。

ased on the action mechanism between the setting load of support and the face upper strata movement caused by the deaf weight,the problem of reasonable setting load that support should have to control the movement of face upper strata has been solved in this paper.
