Slope stability analysis and prediction based on the limit equilibrium method of Luming Molybdenum Mine's West-I and North Region
Abstract
Slope stability is directly related to the safety of the mine production, which is one of the key factors influencing the mining production benefit. Based on China Railway Resources Group Co., LTD Luming Molybdenum Mine’s west-I and north area as the main research background, according to the slope engineering geological conditions and mining design of Luming Molybdenum Mine, this study established the numerical simulation mechanical model for the selected profiles, including three profile of West-Ⅰregion and three profile of North region, analyzed and calculated the safety factor by the limit equilibrium method and Geo-Slope software, evaluated slope stability. And optimization design was carried out on the sections not meeting the requirements, and after the optimization design, the safety factor met the requirements, the slope is generally stable.
