Mine Dewatering
Mines that intersect significant aquifers require pumping from bores and/or sumps to limit the ingress of water to the workings. Open-pit mines commonly need dewatering ahead of mining to ensure wall stability and pit-floor workability. Rockwater designs and implements dewatering schemes - assessing hydraulic properties using: visual inspections; injection/pressure testing; test drilling; bore construction and/or; test pumping techniques.
