Research on Conveying of the Screw Coal Miner

摘要

Motion and force of the solid plug were analyzed in the transportation of screw coal miner. It build the dynamics model of the solid conveying theories. The influences of traction angle, coefficients of friction and helix angle have analyzed. The result showed the soild flow rate of the cases can be improved with the increasing of traction angle and the coefficients of friction between solid plug and mining, lowering the coefficients of friction between solid plug and screw also improved the soild flow rate.
