Abstract：A designed depth of the mine main shaft in Dahaize Mine was 703.96m.Two pair of 45t skips would be set in the mine shaft.The skip height would be 22.2m ,a normal lifting time would be 74.4s , an inactivity time w ould be 45s and a cycle time w ould be 119.4s.From the aspects of the engineering investment ,construction period ,technical reliability and operation efficiency ,a comparison analysis was conducted between the hydraulic weighting type quantitative loading device and the belt type quantita‐tive loading device ,an optimization was conducted on the design of the skip quantitative loading system in the mine main shaft and the belt type quantitative loading device was finally selected.
