Aimed at the process of rope arrangement in double-rope winding drum of super-deep mine hoist, the tension change during rope jumping fault is studied. By analyzing the relationship between the length difference of two ropes caused by rope jumping and tension, the tension simulation model of multi-layer winding drum rope jumping is established in MATLAB, and the results of simulation and experiment are analyzed and compared. The results show that the rope jumping fault will lead to the tension change of the two ropes, and under different rope jumping faults, the tension change law of the rope is different. The simulation model can well reflect the relationship between rope jumping and tension change, and can quantitatively simulate the tension change during rope jumping. These results have important reference value for fault diagnosis research of hoisting system jump in ultra-deep mine.
