Abstract
Based on the developed parametric model of mined-out area in Artemievsk Mine, parameters and anticipated size of accumulated voids and exposures within the limits of Phase I mining are determined. Stability of underground excavations is estimated by the data of 3D modeling of rock mass stress state. Implementation of recommendations will allow safe completion of Phase I and transition to Phase II mining.
