COMBINED SHEME OF ORE TRANSPORTATION AND DELIVERY BY THE DEVELOPING OF VETRENSKOYE DEPOSIT

Abstract

As a result of the revision of the conditions of Vetrenskoye gold deposit, it is stated as actual the involving into the exploitation of the reserves of the lower and worked out upper floors. In order to maintain the production capacity of the underground mine at the level of 200 thousand tons of ore per a year, a set of technological solutions for opening, preparation and cleaning excavation was developed. A scheme for opening the mine has been developed, which makes maximum use of the existing
developments and allowing timely access to all the deposit's reserves, and schemes for delivering and transporting of rock mass from the face to the surface with a two-stage system of ore outlets. A rational procedure for mining reserves of the lower
and upper parts of the field has been established. The compositions of mobile equipment complexes have been set, which ensure the annual penetration volume of mining-capital and preparatory-cut workings, extraction and transportation of ore with sufficient time reserve.
