Abstract:The relationship between the design of the main shaft hoist speed diagram and hoist operating efficiency is introduced. In view of the bottleneck problems arising in the main shaft hoist of the mine, the hoist speed diagram is analyzed, and finds out the nodes which affect the hoisting efficiency in the speed diagram. Combined with the mine practice, the skip crawling distance and crawling time of the main shaft hoist can be shortened, the single lifting time of the hoist can be reduced, and the operation efficiency of the hoist can be greatly improved by optimizing the design and verifying the running speed diagram of the hoist.
