Advanced Mine Water Management Solutions | DHI
In mining, it's vital to keep the bottom of a pit dry. In fact, seepage coming out of a pit wall brings real danger of collapse. To mitigate this risk, DHI can create a highresolution 3D groundwater flow model in FEFLOW specifically designed to evaluate pit groundwater inflows and pit wall depressurisation under various pit configurations ...
Sand And Gravel Processing
Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels, draglines, front end loaders, and bucket wheel excavators. In rare situations, light charge blasting is done to loosen the deposit. Mining by dredging involves mounting the equipment on boats or barges and removing the sand and gravel ...

Mining Techniques of the Sierra Nevada and Gold Country
Hydraulic Mining. Hydraulic mining was a potentially efficient method of getting gold out of the ground, but it was also the most environmentally destructive. The principle was very simple but devastating — water under pressure would be directed against a bank of gravel deposits and the hillside would wash away rapidly. The debris would wash into a series of huge sluice boxes that would ...
