342 delegates from 25 countries attended Mine Water Solutions 2013 conference!
The greatest challenges in managing mine waters arise at mines in extreme environments. Mines in extremely arid environments may require expensive systems to desalinate sea water and transport the water great distances to the mine. Mines in extremely wet settings may need expensive systems to treat excess process and contact water before discharging to sensitive receivers. Mines in extremely cold climates may face frozen conditions and the challenge of operating facilities where most of the water is ice for a good part of the year. Complex hydrogeological and geochemical issues are also common to the extremely wet, dry and cold climate settings.
Mine Water Solutions in Extreme Environments is the first in an innovative new conference series that aims to examine a wide range of issues associated with mine water management in extremely wet, dry, and cold climates and with extreme hydrogeological and geochemical issues. The conference papers attest to the ingenuity of mining professionals in addressing mine water management issues by implementing proactive solutions. The technologies, advances, and case histories discussed in these papers will enable us to move forward and cost-effectively implement solutions at mines all over the world.
We had a pleasure of welcoming to Lima 342 consultants, engineers, managers, researchers and scientists from 25 countries. The technical program included three full days of sessions and was supplemented by three short courses. The conference was held in Lima, Peru, and the gastronomic wealth and traditions of the host country were fully featured at the gala dinner held in the award-winning Huaca Pucllana restaurant.
The following topics were the focus for presentations:
Water Management in Extremely Wet Areas
- Precipitation, prediction of flooding and the influence of climate change
- Diversion design, erosion management and control during extreme events
- Waste disposal challenges and control of impacted water
- Water storage and treatment
- Mine closure
- Laws and regulations
Water Management in Extremely Dry Areas
- Water sources preservation and alternate water supply strategies
- Tailings management to minimize water losses and closure to preserve groundwater
- Managing salts accumulation and dust
- Water desalination
- Water reuse
- Laws and regulations
Water Management in Extremely Cold Areas (Glacial, Periglacial and Permafrost)
- Seasonal effects on water management
- Permafrost characterization, hydrology and water yields
- Cold regions mine site hydrology and hydraulic issues (e.g. ice blockage)
- Dam design, operating practices and mine closure in cold environments
- Climate change design criteria and permafrost impacts
- Mining close to glaciers
