Mine dewatering - Wikipedia

The act of taking water from a mine that is being operated has been done since Neolithic times. In the past it was done by using a shadoof, digging deeper dikes so that gravity would remove the water, by mounting leather water-filled buckets on water wheels or, if nothing else, carrying water-filled buckets manually. The Archimedes' screw was also historically used to pump water out of mines. Where no dewatering techniques were effective the mine had to be shut down due to flooding.

Powerful Mine Dewatering Pumps Systems

Feb 28, 2013  Pumps 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 mine’s biggest enemy. Getting water out—and keeping it out—is the primary focus of any mine plan.

Considerations for Underground Coal Mines That Operate

Mines in the late 1960' s were based on horizontal dril holes in the coal seam that were driled from a shaft sunk into a coal seam (Fields, H.H., et. aI, 1973). Several underground coal mines currently use horizontal in-seam techniques to extract CBM from locations inside the mine. A cross-panel horizontal hole system is shown in Figure 5.
