Mine hoisting equipment is an important equipment in mine, which is related to the safety of coal mine production. Using the construction project of Gepu Mine as the background, the selection and calculation of the sub-shaft lifting system of the mine was carried out according to the demand of the mine production. After accounting and verification of the wire rope, hoist and electric motor, JKMD-3.5×4(III)E type floor-mounted multi-rope frictional hoist with n=42 r/min and 800 kW low-speed direct-coupled DC motor can meet the production needs of the mine's secondary shaft, guarantee the daily efficient operation of the mine and provide reference for other similar mines.
