With increasing depth,the multi-rope friction hoister system is widely used in deep vertical shafts.However,due to the mechanical performance difference,manufacture errors and operational characteristics of the hoister system,the force between steel ropes does not balance during the operation of the system,causing a slide of part of the steel ropes,leading to more hoister system maintenance workload and shortening the life of steel ropes.In light of these problems,based on the mechanism of unbalanced force between steel ropes,in the case study of Chener Gold Mine,type selection calculation of initial rope suspension device in deep shafts is carried out to select the proper initial suspension device.With it,the maintenance operation changes from once every other week to once or twice every year,and the life of steel ropes can basically reach 2 a.
