Cost-efficient Transport for Open-pit Mines | E & MJ
By Dr. Franz Wolpers. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems. Mine trucks that weigh between 106 and 260 tons, and carry payloads from 136 to as much as 400 tons, transport these materials from the pit bottom ...
