Abstract: Abstract: In order to make the fault type, the fault reason and the logical relationship among various faults of deep well hoisting wire rope clear and to find out main factors which affected the failure of deep mine hoisting rope.The fault tree model of deep well hoisting rope was established by using fault tree analysis method and analyzed qualitatively and quantitatively in this paper. The reliability simulation model of deep mine hoisting wire rope was established based on matlab software, the reliability and failure probability density curve were obtained. The results show that the torsion of the wire rope was the main reason for the failure of the deep wire rope. The failure of the deep wire rope was mainly occurred in the early stage when the wire rope was put into use.
