Schemes of Exploitation in Open Pit Mining

2014
The exploitation of open pit deposits usually takes place through a series of mining phases, commonly known as pushbacks. In open pit metalliferous mining, each pushback considers the extraction of one or more benches simultaneously in a process where the core operational tasks include: drilling, blasting, loading and hauling.

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

On the Dynamics of Mining Operations in Open Pit Mines

International Journal of Surface Mining, Reclamation and Environment, 2003
In this paper, mining dynamics is defined as the relationship between the mining rate and movement of mining operations conducted on the benches of a surface mine. This relationship describes the intensity of the pit development in space, in order to meet ore demand at the mill over time.

A Study of Radiation Parameters in an Open-pit Mine

Health Physics, 1982
Radiation parameters associated with the open pit mining of a small (10,000 tonnes), but high grade (2%) uranium deposit at Nabarlek, N.T., have been investigated in detail. External radiation levels, radon emanation rates and radon daughter levels were measured systematically during the development of the mine, and are correlated with ore grade ...
