Hydration of outdoor workers in north-west Australia.
The consequences of environmental heat stress include a reduction in safety due to impaired concentration, a decreased work capacity, and heat illness. Maintaining adequate hydration is the single most important strategy to counteract the effects of thermal stress. In this study, the hydration status of groups of outdoor workers at mine sites and related facilities was assessed. Urine specific ...

Packer Testing Program Design and Management
Abstract: Hydraulic testing using wireline deployed water-inflated packers is becoming a common practice for groundwater characterization at mining sites. Packers, designed for diamond drilling, allow for faster, deeper, and more accurate types of testing conducted concurrently with existing coring programs. Designing and managing these testing programs requires planning, flexibility, and ...

Surface coal mining influences on macroinvertebrate assemblages in streams of the Canadian Rocky Mountains
To determine the region specific impacts of surface coal mines on macroinvertebrate community health, chemical and physical stream characteristics and macroinvertebrate family and community metrics were measured in surface coal mine‐affected and reference streams in the Canadian Rocky Mountains. Water chemistry was significantly altered in mine‐affected streams which had elevated conductivity, ...

Top-down/bottom-up approach for developing sustainable development indicators for mining: application to the Arlit uranium mines (Niger)
Mineral extraction is related to complex sustainable-development issues that are subject to international and local controversies. Debates and decisions need to be based on objective and comparative elements. Defining strong indicators for assessing impacts and performances of mining sites thus appears necessary to inform and support the decision-making process for stakeholders. In recent years, ...

Achieving to some outranking relationships between post mining land uses through mined land suitability analysis
Adoption of most suitable post mining land use is a problem with multi-dimensional nature. There are so many factors in this problem which seriously influence on the decision judgments. Therefore, in this study a fifty-attribute framework for mined land suitability analysis including fifty numbers of economical, social, technical and mine site factors developed to be a foundation for this ...

Using Resistivity for Basalt Site Characterization - Case Study
Purpose A mining company in Turkey hoped to determine existing and new alternative basalt zones at an existing basalt mining site by using Electrical Resistivity Imaging (ERI). Process Our client, Ali Karan, used 84 electrodes spaced at 10 meters and two lines 5 meters apart inside the study area. The dipole-gradient array was used to collect the 2D electrical resistivity imaging data ...

Mining Site - Mining Industry, Santiago, Chile - Case Study
Our prospective client is in the copper mining industry in Chile, where they pay twice as much for their electricity than counterparts in neighboring countries. Electricity consumption in such industry is projected to double by 2025 in Chile and there is an urgency to ramp up their power capacity to meet future demand. Solar energy has long been touted to become a major source of clean and ...

Studies on Microbial Heavy Metal Retention from Uranium Mine Drainage Water with Special Emphasis on Rare Earth Elements
Microbial heavy metal retention was studied using seepage water sampled from a former uranium mining site in Eastern Thuringia, Germany. The seepage water has a low pH and contains high concentrations of metals, including uranium, rare earth elements (REE), and other heavy metals. Microbial influence on sorption and/or active uptake of heavy metals was studied using REE patterns. Incubation of ...

Wavelet–based models for air pollution modelling around coal mining sites in Jharkhand for 1, 3 and 5 day lead time
Coal dust is a major cause of air pollution in areas around opencast coal mining sites. Prediction of ambient concentration of pollutant should be known to implement any control techniques or to install any control equipment. Combining adaptive network based fuzzy inference system (ANFIS) and linear regression (LR) with discrete wavelet transform (DWT), two types of hybrid models were developed ...

HVSR-Aided Monitoring of Embankment Integrity - Case Study
Perth, Australia Fortescue Metals has recently studied the applicability of the HVSR method to the assessment of mining embankment integrity. Embankments are common features in mine sites, necessary for tailings storage, surface water management or general infrastructure such as dewatering ponds. Even though their construction methodology can largely vary, the degree of compaction is a ...

Prj 9712 - Underground water decontamination at a Copper Mine Site - Case Study
Starting May 1997, on authorization from BHP Copper (Tucson, Arizona) a BIOREM lab test was performed on underground water from BHP Miami-Globe mining operation (Arizona). Samples consisted of contaminated underground water and some alluvial soil taken in the vicinity of the well. The soil made possible the set-up of two columns as in figure. From water and soil there were selected the ...

Performance of sulphate- and selenium-reducing biochemical reactors using different ratios of labile to recalcitrant organic materials
Successful operation of sulphate-reducing bioreactors using complex organic materials depends on providing a balance between more easily degrading material that achieves reasonable kinetics and low hydraulic retention times, and more slowly decomposing material that sustains performance in the long term. In this study, two organic mixtures containing the same ingredients typical of ...

Environmental monitoring on mining sites - Case Study
Environmental monitoring on mining sites Mining generates dust and noise pollutions that impact health and environment. As we become more cognizant of the impact mining dust has on air quality, public protection agencies have passed regulations to decrease the impact mining may have on human health and the surrounding communities. Worker safety has long been at stake as well, and new ...

Gruyere Gold Project, South Dorothy Hills, Western Australia, Australia - Case Study
Project Summary Project The Gruyere Gold Project began in October 2013 when Gold Road Resources Limited discovered one of the largest undeveloped gold deposits in Australia. After its discovery, Gold Road mined 148 million tons of gold, grading 1.3 grams per ton for 6.2 million ounces of contained gold. With this large amount of metal, Gold Road needed a way to manage the project and ...
