Security Control And Optimization Design Of High Slope

With rapid construction and economic development in our country, a lot of natural resources is needed, so a number of artificial high slopes are formed. If those high slopes lose stability, it will cause huge disasters, and deep mining disturbance is one of the important factors that induce high slope instability. Because of the complex geological conditions of high slope, how to ensure its stability becomes an important research direction of deep mining. This paper is based on Buzhaoba Open-pit Mine to do the analysis and reseach of the high slope stability. This paper presents a variety of governance programs and receives the optimized solution, and the main contents are as follows:1. By using the critical slip field technology and various limit equilibrium methods to analysis the Buzhaoba Open-pit Mine of present slope, it find that the342section and344section are both in critical state. The sections need to be governed to ensure the safety of the mining. After using drainage and load reduction comprehensive measures, the342section and344section are both in stable state, and it can meet the requirements of the mine safety.2. By using the critical slip field technology and various limit equilibrium methods to analysis the Buzhaoba Open-pit Mine of final slope, it finds that the342section and344section are both in unstable state. To ensure the recovery of the deep resources, this paper presents six governance programs and receives the anchor pile governance program as optimized solution.3. Six kinds of slope management program are analyzed from the price of raw materials and other various influence factors. By analyzing the cost of six programs, it is concluded that the optimal management program.
