THE USE OF SLOPE HOISTING PLANTS TO CREATE THE CONDITIONS FOR CIRCULAR TRAFFIC OF DUMP TRUCKS

English abstract

The purpose of this article is to develop and substantiate rational designs of slope hoisting systems for dump trucks in the open pit mines. In order to reduce the time losses associated with idle mileage in the transport cycle, it is proposed to use the slope hoisting plants only for hauling down the empty trucks. The basic arrangements of slope hoisting systems have been analyzed. A rational field of using them has been determined. The lack of experience in operation of slope hoisting systems with multi-rope friction winders, the possibility of reducing a friction ratio due to freezing and wetting the rope leave no chance to recognize this technical solution to be reliable. The article presents the results of the design study and determination of parameters of a hoister with a reeving system of suspension of one platform to haul down the 130-ton trucks. The developed hoisting plant consists of the main parts as follows: two 1-65.6/0.8 single-drum hoisters; a platform for transporting the truck; a headframe for placing the deflection sheaves; two deflection sheaves; two inclined rail tracks to move the platform. The article proposes the new technical solutions for hoisting plants with two platforms, which are alternately used for hauling down the empty trucks. The developed technology promotes improvement of the operational performance of dump trucks in the open pit mines.
