May 24, 2018 Design of an Optimal Dewatering System. Description of Example Problem. A circular open pit mine is to be excavated to a depth of 750 ft below the original ground-water table over a 10-year period with progressive mine stages at 2-year intervals as shown on Figure 1.
Mine dewatering is a production critical function inflow of waters needs to be removed to maintain a safe production environment. In order to ensure redundancy, the pumping system must include spare pumps and parts. In a three-unit system, any two pumps need to be able to provide the maximum inflow. ... When considering design, the following ...
The dewatering aspects of transition from open pit to underground mine is also covered. You will be educated in the basic theory of mine dewatering and the application of the knowledge to real world situations. The steps required to design and implement a successful and cost effective dewatering
Feb 28, 2013 Pumps amp Systems, March 2013 Mining applications are as diverse as construction or water and wastewater applications. Each jobsite has specific requirements and needs. Underground and open pit mines have several layout and design obstacles. Regardless of the mine and its setup, water is a mines biggest enemy. Getting water outand keeping it outis the primary focus of any mine plan.
The design of a dewatering system will be specific to the mine under scrutiny. To achieve the best method of dewatering a multi disciplinary approach is recommended

The time required to achieve a dewateringdepressurization target is an important design consideration, so these analyses are based on models considering transient groundwater flow. Singh and Atkins 1985 provide a compilation of analytical solutions useful in the estimation of groundwater inflows to mine
Nov 23, 2013 Groundwater Investigation Techniques Groundwater investigations can play an important role in the design of mine dewatering systems. Groundwater investigation techniques include Borehole permeability tests A range of tests can be carried out in individual boreholes, including rising and falling head tests, constant head tests, Lugeon tests ...
flow, mine dewatering and groundwater injection of saline and brackish water. Ultimately, the model could be used to Design practical dewatering and reinjection solutions to meet specific water management goals Optimise designs for economic efficiency Evaluate potential effects of

Oct 29, 2020 Groundwater inflow to an underground mine will seriously affect its mining plan and engineering geology safety. Groundwater models are powerful tools commonly used in the mines to develop dewatering strategies. Many mines in the Kolwezi area have been present since the 1950s, and groundwater flow patterns have been significantly influenced by mining activities.
Our team completed a detailed hydrogeologic characterization of the carbonate aquifer to delineate its extent, defined the life-of-mine dewatering requirements, and developed the design of the open-pit dewatering operation, while meeting the mines water-supply demand and complying with environmental regulations for discharge of excess water.
The bulk of the worlds minerals come from open pit mines where large volumes of rock must be moved while keeping costs low. Since profit margins depend on cyclical metal prices, optimal mine design and scheduling are vital.
Nov 20, 2017 I recently visited an underground mine where the population of electric submersible Dewatering pumps numbered close to 80 pumps. Up to the first 6 months of this year 2017 the mine had spent close to 600k on pump repairs and replacements.
A system and method for efficiently and effectively removing water from mine areas is presented. In one embodiment, one or more directionally drilled dewatering wells are drilled into the geologic formation such that at least a portion of the dewatering well is positioned underneath the mine. In one embodiment, one or more of the dewatering wells may originate outside the perimeter of the mine ...
Dec 17, 2011 Mine dewatering pumps generally need to pump water horizontally-from a smaller sump to a larger sump-or vertically from the bottom of the pit up to the elevation of the mine, and then horizontally to a discharge point. ...
