爆破影响下露天矿边坡的稳定性分析

Stability Analysis of Open-pit Slope under Blasting Influence

针对露天矿山边坡在爆破影响下受结构面控制的稳定性问题,以某石灰石矿山工作台阶边坡为研究对象,在统计分析研究区优势结构面的基础上,利用离散元软件3DEC对工作台阶边坡在自然状况及爆破影响下的稳定性状况进行了定性与定量研究。研究结果可为矿山设计与安全生产提供参考。

Aiming at the problem of open-pit slope stability controlled by the discontinuity under blasting influence,the working bench slopes of a limestone mine was taken as the research object, and based on the statistical analysis of preferred discontinuity in the study area,the qualitative and quantitative study was carried out on the stability of the working bench slope under the natural condition and blasting influence by using the discrete element software 3DEC. The results can provide reference for the mine design and safe production.
