Mine dewatering - QueensMineDesignWiki

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.

Dewatering Mines Pumps Systems

Dec 17, 2011  Dewatering Mines. by Stephanie E. Morgan, Godwin Pumps. 12/17/2011. There are two largely accepted facts about mining: 1) A mine's landscape is dynamic, and 2) Within that landscape, water is a mine's worst enemy. Navigating a mine's landscape with pumps designed to move and/or remove water has long been the challenge of mine operators.

An Introduction to Design of Dewatering Systems

2.1.1 DESIGN. Design of a dewatering system requires the determination of the number, size, spacing, and penetration of wells or wellpoints and the rate at which water must be removed from the pervious strata to achieve the required groundwater lowering or pressure relief. The size and capacity of pumps and collectors also depend
