Abstract

The possibility of using the ascending order of mining deep horizons of the Zapolyarnoye deposit at the Severny mine of the Kola MMC instead of the currently used descending order of development system with sub-stage ore excavation and backfilling of the mined space with solid monolithic backfill is considered. It is proposed to switch to a two-stage development of chambers with the use of combined stowing in the ascending order of excavation within the entire field: solidifying monolithic stowing of the I stage chambers and rock stowing of the II stage chambers. Monolithic solid stowing serves as a retaining wall when excavating phase II chambers. Calculations according to the Coulomb theory allow us to consider the ratio of phase I and II chambers sizes equal to 1:7 to be expedient. Replacement of solid stowing with combined stowing, most of which is represented by rock, as well as transition to increased height of chambers will reduce the cost of extracted ore and improve the geomechanical situation in the host rocks.
