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.

We are installing dewatering bores in a variety of geological environments, including faulted and weathered crystalline bedrock, buggy and fractured chert, dolomite and banded iron-formation, clastic and chemical sediments within sedimentary basins, buggy and cavernous, and highly porous concretized lamproite associated with diamond pipes. Rock conditions are often challenging, involving the use of diverse drilling techniques, such as air-rotary, air-hammer, mud-rotary and dual-rotary.
