Open pit mining robotization

2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017
In open pit mining development there is a world trend to increase the unit capacity of mining equipment, robotization of the processes of blasting, loading and transportation of rock mass. At the same time, unpredictable spatial variability of structural and strength properties of rocks does not allow one to conduct high-quality operational and current

Ultimate Pit Limit Determination Considering Mining Royalty in Open-Pit Copper Mines

2019
Mining royalty is a payment to the holder of mineral rights for utilization of the mineral resources. As well, the royalty is recognized as the amount of mining contribution in sustainable development. So far, there has not been a generalized world acceptable approach to examine the effects of royalty on mine design elements such as cut-off grade ...

Determining waste mining capacities for open pit mines

Proceedings of the Fourth International Seminar on Strategic versus Tactical Approaches in Mining, 2011
It often happens that there is misalignment between the tactical (short-term) and strategic (long-term) mine plans. One scenario where this problem becomes evident is where a dramatic increase in the waste mining rate is required in the long-term that exceeds the practically achievable short-term capability.

Electrification of large open-pit copper mines

Electrical Engineering, 1944
The transportation problem of a large strip mine involves the loading, hauling, and dumping of both ore and waste. These materials are loaded with large electric shovels operating on benches along the slope of a hill or pit. The ore is transported over main-line tracks to the reduction plant, while the waste is hauled to suitable dumps.
