Abstract
The use of sublevel caving with an upward and undercut-and-fill stoping for mining Northern ore body of the Orlovsky deposit based on the numerical simulation of the rock mass stress-strain state using the finite element method is substantiated. It is determined that undercut-and-fill stoping with a backfilling layer 8 m high is a safer option in the conditions of lower horizons of the deposit, from the viewpoint of enclosing rock stability.
