Abstract In this paper, rope and more friction-mine hoist the development and application, type and structure of a comprehensive elaboration of multi-rope friction-mine the advantages and disadvantages of upgrading the classification and study of multi-rope friction demonstration enhance the work of principle; introduced a multi - - Rope friction-mine hoist the various models in principle that brake work on the basis of a selection of the brake. With a specific mine coal mining and geological conditions, the multi-rope friction-mine hoist a selection of equipment, a set of comprehensive mine hoist system, the whole system of electronic control is very important, so the final design of the system The control design. Multi-rope friction-mine hoist system of the Selection System Model, and the layout of the unified system, the system determine the location and size of these multi-rope friction-mine hoist in practical application to provide the necessary Parameters.

Keywords: multi-rope friction-mine hoist; Selection; braking; system . . . .
