Abstract: Aiming at the problems of multiple lengthy links, low transportation efficiency, low reliability and low safety of Bayan Gaole Coal Mine Auxiliary Transportation System, through the research and analysis of the downhole transportation conditions in the coal seam at 311202 working face of Bayan Gaole Coal Mine, a comparative analysis was made. The working efficiency under different reloading modes has been proved by practice; with the method of "container reloading mode", the auxiliary transportation efficiency of the mine has been greatly improved. Relying on the upgraded and improved transportation equipment will increase the output of coal mines, reduce production costs, and increase auxiliary transportation. Level is important.
