Belt conveyors are mainly used to transport coal underground in coal mines.Due to the existence of grade change points in the roadway,the concave arc section may have a large curvature radius during transportation,which can cause the belt to jump off the rollers and have a certain impact on the stability of the belt conveyor.Therefore,in order to prevent the occurrence of belt flapping in the concave arc section of the conveyor,a comparative analysis was conducted on three schemes:expanding the roadway,adding pressure belt devices,and secondary unloading segmented transportation,and the optimal scheme was selected.
