DEVELOPMENT SYSTEM OF THE JOINT DEPOSIT “YOSHLIK I AND KALMAKYR”

Successful experience of exploitation of stockwork copper-molybdenum deposits, in particular the Kalmakyr site, has shown that application of the transport system of development with movement of waste rock to external dumps for specific mining and geological conditions of the combined deposit "Yoshlik I and Kalmakyr" is the only acceptable solution. Development of the deposit "Yoshlik I and Kalmakyr" is envisaged by the open pit method. In accordance with the mining and technical conditions of the deposit, the adopted development system is deepening (prof. V.V. Rzhevsky) with variable position of the working area and transportation of overburden rock by combined transport to external dumps. Ore is transported in two directions: - from the Kalmakyr site - in option No. 1 by rail, in option No. 2 by conveyor transport to the processing plant (MOF-1), located northwest of the combined deposit; – from the Yoshlik I site – from the DPU CPT ore West by conveyor transport to MOF-3, located southwest of the combined deposit.
