Red Hill Mining Lease EIS │Appendix I2│Mine Water Management Overview Report Page 2 – means for providing flood protection to the mine access and MIA, potentially requiring a levee along the west bank of the Isaac River. • A potential new Red Hill underground mine expansion option to the east of the GRB mine complex,
Water accumulation and related hazards can put workers in underground mines at risk. These hazards can cause serious injuries, and even death, to workers. Incidents can be prevented by ensuring: Pumping systems (sumps) are capable of removing excess water from the workplace.
Dec 17, 2016· Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
Every day, your mine sends countless messages in the form of data. Are you listening? We make sure you can hear the insights that data provides, then use them to get more out of your operation. More productivity. More efficiency. More profitability with Underground Mining Technology.
MINIMIZING ACID MINE DRAINAGE BY SURFACE AND SUBSURFACE WATER HANDLING PROCEDURES By John D. Robins Robins and Associates Charleston, West ia One of the most serious potential environmental problems resulting from coal mining operations is the formation of acid mine drainage. Acid mine drainage is an extremely
picture : accident because water inflow to a mine. Past experience indicates that there are four distinct modes of underground water inflow to a mine which has an important influence in designing pumping capacity. These inflow modes are: a) Constant Rate of Inflow over a Long Period
The coal mining industry is facing serious corrosion problems. Millions of litres of water is disposed off from some underground coal mines every day. In this survey, mine water samples from various underground coal mines were collected and analysed in an attempt to correlate the various physicochemical characteristics with their corrosivity.
Gravity usually is employed wherever possible to move broken ore from stopes to the haulage levels, and orepasses from the stopes terminate at the bottom in chutes, by means of which the flow of the ore into cars or onto conveyors can be controlled.

The Southern African Institute of Mining and Metallurgy Platinum 2012 177 M. Karsten, L. Mackay UNDERGROUND ENVIRONMENTAL CHALLENGES IN DEEP PLATINUM MINING AND SOME SUGGESTED SOLUTIONS M. Karsten BBE Consulting L. Mackay Impala Platinum Ltd Abstract Platinum mines in the Bushveld Complex are located in areas with a high geothermal gradient.
majority of emissions can be found in discharged mine water. As mine water accumulates when the water level overflows the depth of an open pit surface mine or an underground mine, the water must be pumped or drained out of the mine to ensure safety and stability. Depending on the water availability and quality, it may be reused for
Drifts/Inclined Shafts/Declines. Excavation methods for drifts are likely to be the same whether straight or with a change of direction. There are 3 methods which .
underground loaders and trucks are engineered for safety, productivity and reliability in even the toughest applications. Rugged, compact and highly maneuverable, these equipment offer impressive capacity for their size, and a low cost per tonne.
Mine closure and downdip mining are also considered in reducing acid mine drainage formation. The design of waterhandling systems in a mine is covered in detail. The system must be integrated throughout a mine. Methods of determining pump requirements and size, pipe sizing, and various types of acid mine drainage treatment are discussed.
MineWater conducts insitu and conventional water treatment at mine sites in North America. MineWater can rapidly deploy water treatment strategies at complex sites, and with its partners and affilates can develop publicprivatepartnerships and other financing mechanisms to facilitate solutions.

Aug 21, 2013· Managing water consumption in mining. Share. ... In many cases, especially with underground mining, water needs to be pumped away from a mine site, which can reduce the levels of ground water, deplete surface water or cause pollution to local rivers. Water awareness and investor pressure on industry.
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...
