A set of mobile high-angle conveyors for the transportation of mined rock from deep open pits is proposed in this paper. With a low hoisting height of one mobile conveyor, for example 30–50 m, up to 5 mobile conveyors will be required to hoist the mined rock from a depth of 200 m. The low hoisting height of one conveyor allows to reduce the
