An Uncertainty-based Transition from Open Pit to Underground Mining
There are some large scale orebodies that extend from surface to the extreme depths of the ground. Such orebodies should be extracted by a combination of surface and underground mining methods. Economically, it is highly important to know the limit of upper and lower mining activities. This concern leads the mine designers to the transition problem, which is one of the most complicated problems...
متن کاملScheduling Tools for Open-Pit Mining Operations
In open-pit mining operations, there are several levels of planning, each of which passes down restrictions to the level below. Each planning task is to determine the order in which material should be mined and how it should be processed, such that blending and utilisation targets are met. The mining operations are subject to various constraints on equipment use, maintenance and other resources...
متن کاملA heuristic approach for multi-stage sequence-dependent group scheduling problems
We present several heuristic algorithms based on tabu search for solving the multi-stage sequence-dependent group scheduling (SDGS) problem by considering minimization of makespan as the criterion. As the problem is recognized to be strongly NP-hard, several meta (tabu) search-based solution algorithms are developed to efficiently solve industry-size problem instances. Also, two different initi...
متن کاملOpen-pit mining geomorphic feature characterisation
Among the anthropogenic topographic signatures on Earth, open-pit mines are of great importance. Mining is of interest to geomorphologists and environmental researchers because of its implication in geomorphic hazards and processes. In addition, open-pit mines and quarries are considered the most dangerous industrial sector, with injuries and accidents occurring in numerous countries. Their fas...
متن کاملScheduling in iron ore open-pit mining
During the last few years, most production-based businesses have been under enormous pressure to improve their top-line growth and bottom-line savings. As a result, many companies are turning to systems and technologies that can help optimise their supply chain activities. In this paper, we discuss a real-world application of scheduling in the mining industry. This is a highly constrained probl...
