基于重标度极差分析法的排土场边坡变形监测数据分析

Analysis of dump slope deformation monitoring data based on the rescaled range analysis method

以先锋露天矿代理堡箐排土场为例,采用重标度极差分析方法对露天矿边坡变形监测数据进行分析。研究结果表明:先锋露天矿总体稳定性主要与X方向的变形有关,目前边坡顶部和坡脚变形具有增强的趋势,但趋势不强,仍具有一定随机性,边坡总体是稳定的,后期应着重监测Z方向位移的拐点。相关结论可以作为先锋露天矿边坡安全管理的依据,也可以供条件类似矿山参考。

Taking Dailibaojing dump in Xianfeng Open-pit Mine as an example, the article uses the extreme scale extreme difterenee analysis method to analyze slope deformation monitoring data. The results show that the stability of Xianfeng Open-pit Mine is mainly related with X direction, the slope top and slope deformation has a increasing trend, but the trend is not strong and still has a certain degree of randonmess, the slope is stable on the whole. The latter should focus on monitoring the displacement of Z direction of the inflection point. The relevant conclusions can be used as the basis for the safety management of Xianfeng Openpit Mine slope, which can also be used as a reference for similar mines.
