Stability analysis and movement process determination of rock masses under open-pit to underground mining conditions

Underground mining under an open-pit slope results in movement and instability of rock masses. However, most mass prediction methodologies are empirical only suitable for underground mining. In this paper, a new theoretical methodology is proposed to predict the masses caused by mining, combining two influences, slopes Considering influence open pit on damage patterns, double-slip surface deflection failure model compared with conditions. The critical value sliding body area location were derived based limit equilibrium state determined using vector sum method, verified particle flow program. Additionally, base friction tests used assess suitability processes. moving boundary conditions discovered be deflected larger than process was bottom goaf collapse-middle deflection-top cracking, pattern traction landslide passing from surface, which differed uneven subsidence These revealed that reasonable predicting
