This paper takes the spiral transportation unit of coal mining equipment used in thin coal seams as the research object.Based on an overview of the coal mining machine and the spiral transportation unit,a simulation model of the spiral transportation unit is constructed using EDEM software.Taking the three key process and structural parameters of screw rotation speed,pitch,and screw spacing as optimization objects,and the transportation capacity and stress of the structure as optimization objectives,an optimization scheme was designed based on orthogonal experimental method.Through research,it was ultimately determined that the screw rotation speed is 100 r/min,the pitch is 414 mm,and the screw spacing is 505 mm.The application of the new spiral transportation unit in the practice of coal mining machine engineering has been found to have good results through nearly 10 months of on-site application,which can create good economic benefits for the enterprise.
