Aiming at the problem of fluttering belt which is easy to occur when the belt conveyor with big inclination angle meets the slope change section suddenly during the operation,two anti-fluttering belt prevention schemes used in a mine of Xishan Coal and Electricity Group are introduced,one of them is to prevent and control the fluttering belt problem of the belt conveyor by installing additional pressure belt pulley and decreasing the curvature radius of the belt conveyor,and the other is to prevent and control the fluttering belt problem of the belt conveyor by adopting the lap jointing of two belt conveyors,and the advantages and disadvantages of the schemes of the belt conveyor are analysed in comparison.Comparison and analysis of the advantages and disadvantages of this anti-belt-drifting programme,proposed a reversing roller installed in the combination of steel frame,the conveyor to carry out two unloading,reversing roller based on the transfer of anti-belt-drifting strategy,and application verification.Application results show that:after the application of this new type of anti-belt conveyor fluttering belt strategy,the belt conveyor belt running to the point of change in slope,no longer fluttering belt problems,and achieved better application results,can be similar to the conditions of large inclination belt conveyor change in the point of the slope of the fluttering belt to provide a reference to the management of the problem.
