OPEN-PIT OPTIMIZATION .1. OPTIMAL OPEN-PIT DESIGN

open access: yes, 1993
Optimal open-pit design is, essentially, a computer-based implementation of an algorithm that is applied to a three-dimensional block model of an orebody. The first computer algorithm, published in 1965 by Lerchs and Grossmann, has spawned one of the most active areas of operational research in the minerals industry. Although this algorithm was, for at

DEGRES: A software to design open-pit geometry and to draw open-pit plans

International Journal of Surface Mining, Reclamation and Environment, 1992
Abstract Within the framework of the global DEGRES software, dealing with geotechnical stability in open-pit mines, some computation tools have been implemented to build a numerical model, called geometrical pit model, to modify it and to manage it. The efficiency of the system has been tested in the case of the Sainte-Marie coal mine (Carmaux, France)

Ultimate open pit stochastic optimization

Computers & Geosciences, 2013
Classical open pit optimization (maximum closure problem) is made on block estimates, without directly considering the block grades uncertainty. We propose an alternative approach of stochastic optimization. The stochastic optimization is taken as the optimal pit computed on the block expected profits, rather than expected grades, computed from a ...

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.

A PRACTICAL APPROACH FOR OPEN PIT DESIGN AND VISUALISATION

Mineral Resources Engineering, 2000
In this study, a practical and simple system for design and visualisation of open pits has been developed. The developed mathematical model and visualisation technique have been presented in details. A set of co-ordinates on polygon of pit bottom is used to expand the pit with a certain slope angle, bench height and width. Co-ordinates of each expanded

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
