Zinovyev S. Ground of parameters of equipment for rope dehydration of mining hoisting installation

The interaction of air current with water film on a surface of moving hoist rope of mining hoist is investigated. The mathematical model of water carrying and deleting are developed. Analytical expressions for intensity of carrying water by hoist rope and intensity of removing water from hoist rope surface depending on parameters of equipment are found. These equations are confirmed with experiments in the laboratory and mine. The parameters of the equipment for rope dehydration are grounded. Use of this parameters guarantees complete deleting of water from rope surface with probability of 95%. The methodical recommendations for ground of rational parameters of equipment for rope dehydration are developed and introduced. The idea of water-deleting device is used in the methodical recommendations. The introduction of equipment for rope dehydration will make the 600 thousand UAH of expected annual economic effect due to running costs reduction.
