Abstract. Due to the long-term collapse of consumer prices in the global iron ore market, cost of the iron ore produced by the deep open pits with steeply dipping deposits, can be reduced by re-ducing costs of stripping operations and expenses for the dump formation and rock transportation. It is propose to solve this problem by involving into development geological reserves under the existing system of the vehicle and railway exit roads, concentration horizons of complexes with cyclic-flow technology, and points for transferring cargoes from vehicles to the rail transport. Boundary depth of opencast mining of the steeply-dipping deposits should be clarified with taking into account volume of the formed geological reserves under the existing transport commu-nications and changed prices of the iron ore concentrate.

Keywords: iron ore, cost price, existing transport communication, conserved geological re-serves, boundary depth of the open-pit.
