Abstract：During the mine maintenance ,large equipments hoisting ,mine shaft lining ,mine shaft equip‐ments installation and other construction ,a mine shaft sinking winch would be required .When the steel rope tensile failure accident occurred sometime ,serious threats w ould be made to the safety pro‐duction .In order to effectively solve the problem ,an analysis and discussion was conducted on the cau‐ses of the steel rope breaking .A protection design and reconstruction were conducted on the control system of the winch .The PLC control system was applied to the clustered control of the winch .The measuring elements were added on the stress end of the steel rope and the winch in order to have a real time monitoring and measuring the stress status of the rope and the winch and to put an end to the steel rope breaking down accident when the power was off under the abnormal condition.
