Research On Slope Stability In The West Of Xier Open Pit Coal Mine In East Mongolian

Slope is important to the production because of its security and economy.Generally,the steeper the slope angle, the better the economic efficiency of enterprises.but the corresponding to be reduced security problems, security and economy of the contradiction problem. Deformation and failure mechanism of the open pit slope is an important research content analysis and evaluation of slope stability, at the same time the landslide prevention and implementation of open pit mine slope deformation monitoring to provide decision-making guidance.Therefore, the focus of this paper is to study the reasonable design of slope angle, under the premise of security to maximize the open pit mine economic benefits, at the same time, through the research and analysis for landslide prevention measures and deformation monitoring scheme for open-pit mine production safety is to lay a solid foundation deformation. This study focuses on the East Cic Energy Corp two West Opencast Coal Mine in west slope stability issues around the country, in order to improve the economic efficiency of enterprises, should be established to meet the specific study of the optimal slope shape and slope stability control measures and deformation monitoring scheme requires safety coefficient.In this study, through the establishment of the west slope engineering geological model, combined with geological fill Kan and the past engineering geological data to determine the physical and mechanical parameters of rock and soil, the optimal slope design scheme, numerical simulation technology research and analysis of the deformation and failure mechanism of slope. Based on the above results reasonable prevention measures of the landslide and slope monitoring scheme is presented, and provides technical support for the realization of open pit mine safety, efficient production, its practical significance.
