Abstract
The article describes numerical modeling of sublevel stoping using the discrete element method. The study included development of a modeling procedure, creation and calibration of the numerical models, and the result analysis. The optimal design parameters of structural components of the mining system are found, which are promotive of reduced ore losses in sublevel stoping at the Khibiny apatite–nepheline deposits. Some behavioral patterns of rock mass during sublevel stoping are obtained. The mechanism of ore losses is described.
