Application of rope bucket elevators for mine hoisting

Abstract

Transportation of minerals along vertical mine shafts is carried out mainly by skip hoisting. This type of lifting, being an intermittent transportation unit, has a number of disadvantages. The main ones are as follows: 1) the necessity of construction of intermediate tanks (reloading hoppers) in the near-borehole and on the surface, designed to mitigate the unevenness of lifting and transportation on the surface;2) the complexity of full automation of the lifting process due to the need to continuously change the mode of operation of the engine; 3) high specific energy consumption and increased installed power of the engine, caused by the inclusion of starting rheostats and the presence of peak loads at each cycle of lifting.
