Sishanling Iron mine’s auxiliary shaft is 10 m in net diameter and 1 503.9 m in depth.Since its sinking platform adopted 10-rope suspension ,its hoisting safety will be faced with risks like uneven stresses. In order to secure its hoisting safety ,a winch distributed control system was developed to en-sure the platform's synchronous running. A hydraulic automatic tension balance system was deployed at the suspension points. In this way ,the tension difference among each wire rope was eliminated ,avoi-ding dangers like concentrated wire rope stress ,winch overload. An online tension monitoring system was developed and applied for the wire ropes.So ,real-time monitoring of wire rope stress state was conducted ,achieving emergency operation like alarming and stopping when abnormal stresses oc-curred. These three technologies were successfully applied in the auxiliary shaft project of the Sishan-ling Iron Mine ,resulting in secured shaft sinking safety ,improving efficiency for sinking platform lift-ing and descending.
