ZHANG Qianyi
Abstract：To improve the loading efficiency of thin coal seam winning machine,and enhance the mining efficiency and economic benefits of thin coal seam coal resources,the high-power thin coal seam winning machine was took as an example,the influence of the motion parameters and structural parameters of the drum on the loading performance of the thin coal seam winning machine was studied using the discrete element method.Research has showed that the use of internal rotation loading on the drum of thin coal layer winning machines(drum diameter less than 1 300 mm)had a better effect.By using the method of controlling variables,the influence of drum speed and traction speed on the loading performance of coal winning machines was studied.When the drum speed is 45 r/min,the blade lift angle is 13°,and the traction speed is 5 m/min,the drum loading performance is optimal.
