One of the key issues in mining is the hauling system. Truck and shovels are the most widely used transportation equipment in mines. In this paper, a two-phase simulation-based optimization is presented to maximize utilization of hauling system in the largest Iranian open-pit copper mine. In the first phase, The OptQuest for Arena software package was used to solve the optimization problem to p...

This study investigated dispersion and bioaccumulation of mining-related elements from an open-pit olivine mine at Seqi in Southwest Greenland (64° N) using lichens (Flavocetraria nivalis), seaweeds (Fucus vesiculosus), mussels (Mytilus edulis) and fish (Myoxocephalus scorpius). The mine operated between 2005 and 2009, and samples were taken every year within a monitoring area 0-17 km from the ...

Persistent Scatterer interferometry (PSI) represents a powerful tool for the detection and monitoring of tiny surface deformations in vast areas, allowing a better understanding of its triggering mechanisms, planning of mitigation measures, as well as to find better solutions for social and environmental issues. However, there is no record hitherto of its use in active open pit mine in tropical...

Article history: Received 23 September 2016 Received in revised form 31 January 2017 Accepted 7 February 2017 Available online 9 February 2017 Volcanic eruptions on theMoon take place in conditions of low gravity and negligible atmospheric pressure, very different from those on Earth. These differences lead to characteristic lunar versions of hawaiian and strombolian explosive activity, and to ...

Abstract Functional traits can be used to identify various ecosystem processes that are influenced by natural and anthropogenic factors. We tested the hypothesis species composition functional feeding of zooplankton environmental gradients, such as depth, trophic status, ion content. This was in three lignite strip mine lakes Central Poland. Two shallow, polymictic were reclaimed (1994 2008), t...

the emarat pb-zn mine is located at about 80 km south of the city of arak , iran. i the present mine-scale litho geochemical survey 56 hanging wall samples and 37 footwall samples were taken form exploratory tunnels, drillholes and open pit all samples were taken in the range of 0-40 m from pb-zn veins. the relationship between three variables including concentration of zn in wallwork, distance...

Hydrical reclamation of the residual pit Most-Ležáky is part comprehensive revitalisation land affected in past bymining activity with an area 1264 ha. Thus, terms remediation and reclamation, most appropriate way to reclaim theresidual pit, as one final stages long-term activities that have been going on for more than half acentury, occurs under given conditions. The Lake Most, our study area,...
