Opencast mining method is one of the most productive mining methods available at present, which is generally associated with the removal and handling of a huge amount of overburden material. Hence it imposes a serious challenge of dump slope stability and that too, mainly in the case of internal dumps. The study is primarily focused on the stability of dragline dumps and the subsequent development of a rating system to classify the stability of dragline dump profiles. Initially, numerical simulation is executed through RS2 (Version 9.0) software, which is based on the finite element method. Thereafter, simulation results are used to perform the sensitivity analysis of various geometrical and strength parameters of the dump slope, and the two-factor interaction method is also incorporated into the analysis, this method included the dependency of closest parameters while calculating the sensitivity index, and thereafter, it is converted into the rating of each parameter. The strength parameter like the angle of friction and the geometrical parameter like slope angle of the bench between the coal-rib roof and dragline sitting level are assigned the highest rating value. Based on the overall rating of the dragline dump, the dump slopes are classified into various classes, viz., very safe, safe, vulnerable, unstable, and highly unstable. This classification proved to be handy in the quick estimation of the stability of the dragline dump and also gives an idea of designing optimum and safe dragline dump profiles. The developed classification chart has been validated by the previous research works and has found similar results.

露天采矿法是目前可用的生产力最高的采矿方法之一，通常与大量表土的去除和处理有关。因此，这对堆场边坡稳定性提出了严峻的挑战，主要在内部堆场的情况下，也提出了严峻的挑战。这项研究主要集中在拉铲垃圾堆的稳定性和随后的评级系统的发展上，以对拉铲垃圾堆的稳定性进行分类。最初，通过基于有限元方法的RS2（9.0版）软件执行数值模拟。此后，使用仿真结果对倾卸坡的各种几何参数和强度参数进行敏感性分析，并将二因素相互作用方法纳入分析，该方法在计算灵敏度指标时包括最接近参数的依赖性，然后将其转换为每个参数的等级。强度参数（例如摩擦角）和几何参数（例如工作台在煤肋顶板和拉铲索就座高度之间的倾斜角度）被指定为最高额定值。根据拉铲式倾卸垃圾的总体评级，倾卸垃圾的坡度分为各种类别，即非常安全，安全，脆弱，不稳定和高度不稳定。事实证明，这种分类方法对于快速评估铲斗倾卸料的稳定性非常方便，并且还给出了设计最佳和安全的铲斗倾卸料轮廓的想法。之前的研究工作已经验证了开发的分类表，并且发现了相似的结果。
