Method of changing head rope and tail rope for shaft

Abstract

The present invention relates to a method for changing a head rope and tail rope for a shaft, including the steps of changing the head rope and changing the tail rope; the step of changing the head rope includes the steps such as providing a new rope from a balance weight side wellhead to a cage side wellhead, separating the new head rope temporarily, providing a new rope below the wellhead, carrying out balance weight side heading and carrying out cage side heading; the time for changing the head rope and tail rope is significantly shortened, and vertical deviation of a board during driving is relieved since head rope changing sequence is changed; the tail rope is changed by winding stably at the wellhead and paying off from top to bottom, all rear heads of the tail rope are manufactured on a ground, staff is avoided being in a severe environment when making rope tail heads at the bottom, and operation safety is improved. The method also provides reduced continuous operation intensity for workers and better coordinated production.

Description

technical field [0001] The invention relates to a method for replacing head ropes and tail ropes in a shaft. Background technique [0002] With the increasingly severe operating situation of the gold mining industry, the time and safety performance standards for upgrading the system maintenance are getting higher and higher. The existing method of replacing the head rope and tail rope of the vertical shaft generally adopts the method of importing the belt from the bottom to the top, and the tail rope needs to be made at the bottom of the well. The operating environment is harsh, the safety is poor, and the operation efficiency is low and the rope replacement period is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for replacing the head rope and the tail rope of a shaft, which improves the operating environment and improves the rope changing efficiency. [0004] For solving above technical scheme...
