摘要
最终边坡的稳定性历来是露天开采的研究热点之一。为探究乌龙洞石灰石矿终了边坡稳定性问题,在现场勘测调查取样以及室内力学试验的基础上,首先采用赤平投影法对边坡楔形破坏模式进行定性分析,再利用极限平衡法对边坡稳定性进行定量分析。研究表明,矿山两侧边坡整体处于稳定状态,但有可能在动载作用下发生局部破坏,尤其在南侧边坡发生的可能性偏大。根据评价结果,针对性地提出预防边坡事故的安全对策。
The stability of the final slope has always been one of the research hotspots in open-pit mining.In order to explore the end slope stability of Wulongdong limestone mine,on the basis of field investigation and sampling and indoor mechanical test,the stereographic projection method was used to qualitatively analyze the wedge failure mode of the slope,and then the limit equilibrium method was used to quantitatively analyze the slope stability.The research shows that the slopes on both sides of the mine are in a stable state as a whole,but it is possible to cause local damage under dynamic load,especially in the south side.According to the evaluation results,the safety countermeasures for preventing slope accidents are put forward.
