Abstract: The deepening of open pits wich takes place nowdays leads to a deterioration in the operating conditions of mining and transport equipment in the system of cyclic technology with the use of autotransport, which leads to the inevitability of the introduction of cyclic flow technology with the use of lifting belt conveyors, both traditional and special. In this regard, there is a need to assess the possibilities of their use in specific operating conditions. The technical analysis of lifting systems was performed with the use of traditional belt conveyors in the conditions of Lebedinsky, Mikhailovsky MPK, Karelian Okatysh JSC, as well as sandwich belt high angle conveyors, tubular belts with a special chevron belt, and RopeCon type conveyors. It has been established that for open pits with a productivity above 20 million tons/year, the most promising is sandwich belt high angle conveyor, and for open pits with low productivity, up to 10 million tons/year – tubular high angle conveyors.

Keywords: cyclic-flow technology, belt conveyor, high angle, tubular, productivity, length, belt, lifting height, readiness coefficient
