Basics of calculation of rope cargo bremsbergs with variable angle of inclination

Abstract

In practice of development of coal and ore deposits and in non-metallic mines there is a necessity in construction of rope cargo bremsbergs with variable inclination angle. At modern coal mines bremsbergs at inclination angles up to 18° and at relatively significant productivity are equipped with belt conveyors. In mine workings, the angle of inclination of which exceeds 40°, the descent of minerals, as a rule, is carried out on fixed chutes (grates).
