Jul 18, 2018· AUTHOR: Editor of Mining Review Africa, Laura Cornish. Delivering an effective dewatering solution requires an in-depth understanding of the external factors and parameters that may impact a mining operation – and these may change significantly between different mines says Tefo Moholi, Weir Minerals Africa dewatering product manager.

mining engineering: Mine Dewatering

Baski (1) recently referred to underground mine dewatering as "The Anatomy of Anomalous Conditions"--a beautiful title that says much about the interface of art and science in mine dewatering. Mines and quarries occur in developed and remote areas, both of which may be regarded as hostile environments for differing reasons.

Mine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine workings. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require the use ...

Dewatering Mines | Pumps & Systems

The different methods available for dewatering of excavations at constructions sites are executed uniquely as each one has a narrow range of applications. Thus adopting the right method of dewatering for a particular ground condition is always an important and a difficult decision to make.

Mine Dewatering Design and Implementation

Environmental Hazards of Limestone Mining. Limestone deposits exist throughout the world. These alkaline, sedimentary rocks were laid down mostly as deposits on the beds of ancient seas. A valuable natural resource, limestone has many uses in construction, agriculture and industry. Limestone …

Eductor Wells Method of Dewatering Excavations. The method is very similar to the wellpoint method of dewatering; the only difference lies in the usage of high-pressure water in the riser units instead of vacuum to draw out water from the wellpoints. The method uses the venturi principle which is the reduction in fluid pressure that results ...

Jan 31, 2018· Dewatering methods. One of the most common dewatering methods is using dewatering bags. They are made of durable geotextile fabric which can filter water by removing sediments. Usually, dewatering bags are used on construction sites, dredging operations or areas with high water table near the shoreline.

Dewatering for open pit mines and quarries

Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a pre-requisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.

N-ZONE MINING AND DEWATERING PLANS N-Zone mining plans included access via two northerly-trending drifts known as the Hanging Wall Decline and the Main Access Decline. Both drifts originate at the TQR shaft area, and will be located above and below the ore-bodies. Access ramps and drifts will be driven to reach the ore zones.
