Abstract
:In order to ensure a distance economic rationality of the throw blasting- shovel and truck technical operation line in Haer Wusu
Surface Mineꎬan optimized adjustment was conducted on the distance of the previous operation method to establish the relationship
curve was applied to study the relationship between the distance of the throw blasting-shovel and truck operation line and the production
striping study showed that the longer distance of the throw blasting-shovel and truck operation line would be and the lower of the
3
production stripping ratio would endless would close to 1􀆰 86 m / t in
