江西某金属矿露天采区边坡稳定性分析

Slope Stability Analysis of a Metal Mine Open Pit in Jiangxi

露天矿开采中边坡稳定性问题近些年来层出不穷,开展露天矿边坡稳定分析,对矿山安全生产具有重要的指导意义。以江西某金属矿采区边坡稳定性分析为例,本文通过DIMINE软件构建原始地形模型,采用Bishop法、Morgenstern-Price法、强度折减法和三维数值模拟的研究方法,重点考虑了自重及爆破两种载荷组合,分析江西某金属矿露天采区边坡稳定性,结果表明,Ⅴ区张家山边坡整体较稳定,但个别台阶岩体相对破碎,受到局部断层影响,露天台阶存在楔形体破坏、平面破坏的可能。由以上研究可知,江西某金属矿露天采区会有失稳的情况发生,可以采取适当的加固防治措施。

Slope stability problems in open pit mining have emerged in recent years,and it is of great significance to carry out research on slope stability analysis and calculation in open pit mines for safe mine production.Taking the slope stability analysis of Fujiawu mining area of Dexing copper mine as an example,this paper constructs the original terrain model through DIMINE software platform,adopts the research methods of Bishop method,Morgenstern-Price method and strength reduction method and three-dimensional numerical simulation,and focuses on considering two load combinations of selfweight and blasting to analyze the slope stability of Fujiawu mining area of Dexing copper mine,and the results show that V The results show that the overall slope of Zhangjiashan in Zone V is relatively stable,but the rock body of individual steps is relatively broken and affected by local faults,and there is a possibility of wedge-shaped damage and plane damage of the steps.Therefore,the slope of Zhangjiashan in a metal mining area of Dexing can take appropriate reinforcement and prevention measures.
