In this paper, an infrastructure for monitoring remote equipment and solving some of the logistic challenges of operating satellite surface mines is presented. This infrastructure includes strategies for communicating timely and accurate information amongst operators, planners and supervisors, using off-the-shelf network protocols. Advanced data visualization techniques are implemented, so user...

This paper proposes a newmathematical framework for the open pit mine planning problem, based on continuous functional analysis. The main challenge for engineers is to determine a sequence of nested profiles maximizing the net present value of the mining operation. The traditional models for this problem have been constructed by using binary decision variables, giving rise to large-scale combin...

In the case of Roşia Poieni open pit mine level +805 m was established as a daily operating limit; division into benches based on this by dividing horizontal slices with thickness 15 m, equal to height bench. Thus, there were 27 in Curmătura area and 23 Ruginiş area. The general slope angle set at 35°, for which tailings volumes implicitly opening-up coefficient calculated. stability analysis p...

We present an integer programming formulation for the open pit mine production scheduling problem. We strengthen this formulation by adding inequalities derived by combining the precedence and production constraints. The addition of these inequalities decreases the computational requirements to obtain the optimal integer solution, in many cases by a significant margin. & 2010 Elsevier Ltd. All ...

Here we report on a metagenomics investigation of the microbial diversity in a serpentine-hosted aquatic habitat created by chrysotile asbestos mining activity at the Vermont Asbestos Group (VAG) Mine in northern Vermont, USA. The now-abandoned VAG Mine on Belvidere Mountain in the towns of Eden and Lowell includes three open-pit quarries, a flooded pit, mill buildings, roads, and > 26 million ...
