ABSTRACT
The creeping behaviors between hoisting rope and friction lining in the process of deep coal mine friction transmission are investigated in this study. Rope tension during the hoist lifting and lowering process is obtained first. Then, the calculation models of creeping area, creeping quantity and creeping velocity are established. The rope tension and creeping quantity are measured by a self-designed experiment device to verify the model validity. Subsequently, effects of the kinematic parameters on creeping behaviors are explored. The results show that increases of the terminal mass ratio, terminal mass, maximum acceleration, maximum speed cause expanding trends of overall ranges of the maximum creeping velocity, respectively. Less creep is beneficial to improve the friction transmission safety, service life of friction lining and good anti-slip properties. The most effective way to decrease the creep is to increase the container weight.
