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 کاملPit lakes as an end use of mining: A review
Theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. They are typically in a non-equilibrium state with respect to their surroundings. Hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...
متن کاملDinsar Ground Movement Monitoring in the Rural Environment of an Open Pit Mining Area
We present intermediary results using conventional differential SAR interferometry (DInSAR) in a lignite open pit mining area in Germany. All available ENVISAT and ERS-2 scenes since 2002 were used. Due to the area of interest's rural character and vegetation zone, temporal decorrelation is a limiting factor for C-band based interferometric analyses. Additionally a network of twelve Corner Refl...

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...
متن کاملAn Approach to Locate an in Pit Crusher in Open Pit Mines
Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....
