In order to guide the safety mining and increase the supply quantity, this paper through the use of MSARMA-method and the ''MSARMA evaluation and analytical system for slope stability analysis'' based on this method, which aimed at the quantitative evaluating of the slope stability before and after the actual mining below the slip mass, and the sensitivity analysis for the main influencing factor, providing scientific proof for the parameter optimization of open mine surface slope, the security and sustainable exploitation.展开更多
