Optimization of Throw Blasting-Shovel and Truck Technical Operation Line Distance in Surface Mine

In order to ensure a distance economic rationality of the throw blasting- shovel and truck technical operation line in Haer Wusu Surface Mine, an optimiz ed adjustment was conducted on the distance of the previous operation line. A 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 ratio. The study showed that the longer distance of the throw blasting- sho vel and truck operation line would be and the lower of the production stripping ratio would be. The endless would close to 1. 86 m3/ t in tendency. According to the funct ion relationship between the total stripping cost and the distance of the throw blasting- shovel and truck operation line, a mathematics model was established and the C alculation and analysis were conducted. The results showed that when a minimum value of 1.4 km was accepted as the distance of the throw blasting- shovel and truck technical operation line, the total stripping cost would be the minimum.
