The open pit design and scheduling problem is a large-scale optimization problem that has attracted considerable attention during the last 40 years The development of the "know-how" to improve economics of open pit mining projects through the use of mathematical optimization techniques goes back to early 1960's. Unfortunately, up until recently, many of these "optimizing algorithms" could not b...

Zambia’s economy is fueled by copper production, which one of the country’s most important industries. In terms output, Zambia has around five large open-pit mines and eight significant underground mines. Government owns a stake in some these businesses. This article examines economic, social, technological, environmental ramifications mining Copperbelt area Zambia.

In order to catch up with reality, all the macro-decisions related to long-term mining production planning must be made simultaneously and under uncertain conditions of determinant parameters. By taking advantage of the chance-constrained programming, this paper presents a stochastic model to create an optimal strategy for producing bimetallic deposit open-pit mines under certain and uncertain ...

Open-pit mining is one of the main exploiting methods for solid mineral resources. After more than 100 years high-intensity development, there are a large number abandoned open-pit mines and related relics in world. The reconstruction Pumped Hydraulic Energy Storage systems (PHES) from an effective utilization mode underground space recent years. project planning PHES should consider not only t...

Open-pit mining has caused extensive land destruction, including abandonment and reduction in agricultural land, resulting serious environmental problems. Ecological restoration mine reclamation have become important components of the sustainable development strategies Inner Mongolia, China. Therefore, rehabilitation mines is vital attracted widespread attention from Chinese government. In this...

In order to analyze the slope stability in open-pit mines, the structural parameters of rock mass such as persistence and spatial orientation of discontinuities are characterized through field surveys, which involve spending high costs and times as well as posing high risks of rock toppling and rock fall. In the present work, a new application of terrestrial digital photogrammetry is introduced...
