The main hoist is the key link of raw coal lifting transportation,the lifting capacity of which restricts the production capacity of the mine.With the improvement of the degree of mechanization of the mine,the production capacity of the mine is gradually increasing.Improving the mine lifting capacity has become an urgent problem to overcome,in order to meet the annual production demand.On the basis of ensuring production safety,it is necessary to further improve the lifting capacity of the hoist.Based on the upgrading case of hoists in Changyuan Coal Industry Co.,Ltd.,the feasibility and final effect of the upgrading plan of hoist lifting capacity were analyzed from the view of economy and technology.
