For the demand of lower localization costs, less communications costs and higher accuracy of objects tracking under mine pit, weighted centroid localization algorithm based on RSSI is introduced to localize the node. This algorithm shows relatively high accuracy by simulation and is suitable for the localization of mine personnel.

Very little is known about the organisms that are impacted by mine waste in the Berkeley Pit Lake System. However, it is known that if heterotrophic and autotrophic organisms are properly nutrified, they can bioremediate mine waste-influenced areas as a benefit of their physiological processes. However, before any type of bioremediation of an ecosystem can begin, it is essential to gain a funda...

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 ...

Optimisation tools which determine the best layout for access and haulage in an underground mine address an important and difficult mine design problem. The complexity of the problem can be compared to the task of optimising the final pit design in an open pit, together with the pit haul roads required. The strategic design of an underground mine layout must address the location of haulage shaf...

Sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of Iran and most probably the second largest copper mine in the world. This mine is located in the seismotectonic zone of Central-Iran, and 23 Km away from the 150 Km long Rafsanjan active fault.In this study the vulnerability of the west wall of the...

Slope stability analysis is one of the most important problems in mining and geotechnical engineering. Ignoring the importance of these problems can lead to significant losses. Selecting an appropriate method to analyze the slope stability requires a proper understanding of how different factors influence the outputs of the analyses. This paper evaluates the effects of considering the real geom...

Introduction: Workers in open pit mines are frequently exposed to extreme heat stress during hot seasons. Several indices including Modified Discomfort Index (MDI) are used to evaluate the heat stress. The aim of this study was to evaluate the MDI and to investigate its relationship with ISO 7243 standard (Wet Bulb Globe Temperature index, WBGT) and physiological parameters of workers in an ope...

Mining operations at Bingham Canyon Mine, Utah, 2009 by Arbyreed. License: CC BY-NC-SA 2.0 Land worldwide is deeply marked human activity, which became heavier, harder, more wasteful, and permanent after the industrial revolution. The landscapes of Anthropocene encompass riddled proving ground test sites, nuclear wastelands, immense open-pit mines, contaminated lands, disappearing bodies water,...

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...
