Abstract：A tw o deck cage and 2 cage braking ropes w ere required to be replaced in a -600m level mine auxiliary hoisting blind shaft of Qianjiaying Mining Branch. A traditional construction method could not meet the construction period requirement. With a open and wide idea and an active innovation ,a new replacement method of the braking rope w as provided and applied. With the previous hoisting cage and main rope ,the two braking ropes were replaced simultaneously. Thus the work efficiency would be improved ,the construction period completed was two days in advance than the schedule construction period and a rapid construction was relized. The technology would have a less equipment input ,less preparation workload ,a simple operation ,safety reliability ,short construction period ,low cost and oth‐er advantages ,could be promoted and applied to the replacement of the guide steel rope and would have a high promotion and application value.
