Optimization of step parameters of burnt rock slope
LI Xiaojun
Abstract：To explore the specific impacts of varying parameters of burnt rock steps on slope stability,the article takes the northern slope of Dananhu No.2 Mining site as the research subject,adopts the limit equilibrium method to construct slope model,analyzes the current slope stability,and presents the optimization parameters for burnt rock steps above the+475 m horizontal step.The results show that while the overall slope remains stable,certain sections are unstable,specifically the burnt rock slopes above the+475 m horizontal step.By adjusting the parameters of the burnt rock steps,when the northern slope above the+475 m horizontal step is divided into four steps,each with a height of 10 m,a step angle of 45°,and a flat width of 12 m,the safety factor of the northern slope reaches 1.198,satisfying both production and safety requirements.
