摘要

针对某露天采场高边坡滚石灾害,建立了运动学模型,分析不同计算参数下的边坡滚石运动规律并提出防护方案,该研究结论对矿山的安全生产起到一定的理论指导作用。
        Aiming at the rock-rolling disaster of a high slope in an open pit, the kinematics model is established, the law of rock-rolling movement of slope under different calculation parameters is analyzed, and the protection scheme is put forward.The conclusion of this study plays a certain theoretical guiding role in the safe production of the mine.
