Underground mine working changes hydraulic gradient which affect the underground surface water flow pattern. It induces slow inflow of water from, porous soil and rock mass towards the mining excavation. Mine dewatering is the removal of percolated or logged water from mines to ensure the safety of operating personnel and to safeguard the …
An engine pumps up 1000 k g of coal from a mine 100 m deep in 50 s e c. The pumps is running with diesel and efficiency of diesel engine is 25. Then its power consumption will be (g = 10 m / s e c 2): View Solution. Q2. An engine pumps up 1000 k g of coal from a mine 100 m deep in 0.5 s.
Pumping using centrifugal style slurry pumps are still the most common type of pumping system used in tailings slurry transportation. Often, when a tailings trade-off study is performed for a proposed storage facility, the limits of centrifugal pumping are almost always more cost-effective than paste transportation (particularly for high ...

NEMO ® progressing cavity pumps offer you a particularly long service life, for example, when pumping aggressive gold slurry, even without …
The mines, once the beating heart of the region, where giant mountains of metal waste known as slag still dot the landscape, now represent a looming environmental catastrophe.
Pumps designed for pumping slurries will be heavier duty than those designed for less viscous liquids since slurries are heavy and difficult to pump. Slurry pumps are typically larger in size than standard pumps, with more horsepower, and built with more rugged bearings and shafts. The most common type of slurry pump is the …
From the bronze-age to the lithium-age, the mining industry and its pumps remain at the front of humanity's progress. Atlantic Pumps have been innovating for miners and the mineral extraction industry, developing energy-efficient, mine dewatering pump systems and mine-water monitoring and treatment equipment.
