Mine dump slope stability and failure behaviour analysis under geo-mining condition using hybrid numerical modelling 

 - p 667-676 
<br/><br/> Dump slope stability and failure behaviour analysis<br/>under actual geo-mining conditions is tedious for mining<br/>engineers. Therefore, the present study presents a novel<br/>hybrid numerical modelling for dump slope stability<br/>and failure behaviour analysis, from initiation and<br/>transport to overburden (OB) deposition. Mixed and<br/>broken material matrix slope stability was analysed using finite discrete element method (FDEM). The present<br/>study used absorbing boundary conditions under gravity<br/>force. The shear strength reduction approach was used<br/>for slope strength analysis. Newton’s second law is incorporated to simulate rock boulder kinematics accurately during the progressive failure. The results of the<br/>present study indicate that hybrid numerical modelling<br/>can evaluate dump stability and simulate the complete<br/>failure process, including crack initiation, propagation<br/>in slope, failure surface, OB transport and deposition.<br/>Finally, the role of mixed materials (soil and rock<br/>boulders) in the dump slope stability and failure behaviour was analysed. FDEM is a powerful visualisation<br/>tool for solving a numerical model under real geomining conditions. This will be helpful for the safe<br/>working distance analysis from the dump slope toe.
