Study on stability analysis of typical slope of a limestone mine
Taking a newly-built open-pit mine in Sichuan Province as an example,a typical hazard design profile is selected and comprehensively evaluated by stereographic projection analysis,simple plane sliding analysis,wedge failure analysis and limit equilibrium method.in order to provide reference for the design of high and steep slope of similar newly-built mines.The results show that the cutting of the rock structural plane has a great influence on the slope,and the weathered mudstone at the top of the slope can not be mined beyond the boundary due to the limitation of the mining area boundary,so the wedge failure may occur and the mining scheme in this area needs to be further adjusted;the local stability of the slope top of the typical section does not meet the requirements of the specification,and the structural parameters of the final slope need to be further adjusted in order to ensure the safety of mine production.
