A Stability Classification System for the Dragline Dump Slope

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