Cost-efficient Transport for Open-pit Mines E & MJ

2020-4-8  Cost-efficient Transport for Open-pit Mines. An innovative technological approach to skip haulage could optimize costs and energy efficiency in hard rock mines. 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.

Contribution to Cost Estimation in Open Pit: Aggregates

It is assumed that the cost of mining ore is the same as that of mining waste. The cost of mining comprises drilling, blasting, Ioading and hauling, (in addition the cost of crushing). The cost of open pit mining can be assessed using the total ore and waste (T) mined daily (Table 1).
