Defect analysis and safety assessment of mine hoist wire rope based on hierarchical analysis

Abstract

The hoisting wire rope is an important load-bearing component in the mine hoisting system, and its safety condition is directly related to the normal production of the mine and the life safety of the personnel. Therefore, it is necessary to carry out the research of online inspection technology and safety evaluation method of hoisting wire rope. In this paper, first of all, using denoising and sample interpolation has given the data of six wire ropes ten times round trip for data processing, using the quadrature method for defect analysis; secondly, the wire rope defect density, the number of defects, the spacing of adjacent serious defects and defect size and other 5 factors using hierarchical analysis method processing, its safety performance for the overall assessment.
