Abstract: The dumping plough is used in the dump with high slope,after the determination of the maximum height allowed by steps,in order to select the optimal dumping technique of the lower steps of the dump with multiple steps transported by the one with high slope and single step,the feasible dumping techniques and their adaptive are analyzed,the dumping techniques of chute humping-automobile transportation and dumper transportation are analyzed emphatically,the results show that the economic indicators of investment and transportation cost of the former are superior to the later,which can provide some technical reference for the slope optimization and governance of the dumps with high slope.

Key words: Dump, High slope, Chute, Belt conveyor, Automobile transportation
