Abstract：In order to reduce the impact caused by the wear fault in line pane of scraper conveyor and improve wear resistance, the development of wear characteristics and wear resistance optimization were reviewed, including the theoretical studies about wear forms, wear causes, wear morphology and wear areas, the experimental studies about transport conditions and coal bulk properties, and the simulation analysis about discrete element method and coupling with multi-body dynamics. Including wear-resistant materials, surface strengthening technology, structural improvement and bionic design, four methods to improve the wear resistance in line pane were summarized. It is suggested that the next direction of the research of wear characteristics is to study the intrinsic nature of wear and the quantitative study of wear. The research of wear-resistant optimization should focus on saving cost and applying wear-resistant technology to real scraper conveyor production as soon as possible. The nonlinear theory method is used to predict the wear quantity of the middle groove, and the wear characteristics and wear resistance optimization are studied from the interaction between the friction pairs of the middle groove.
Keywords：scraper conveyor; line pane; friction; wear resistance optimization
