Nov 02, 2018· The essentials of dewatering pit and mine reclamation remain the same. Pit and Mine Dewatering Quarries, pits, and mines can unfavorably affect surface and groundwater in several ways.
The primary dewatering strategy focused on reducing groundwater levels with high-capacity vertical pumping wells in permeable zones around the perimeter of the pit to dissipate pore pressure in the pit walls. The secondary dewatering strategy focused on depressurization of lower-permeability zones along the pit perimeter and inside the pit.

Effective water management is critical in both open-pit . and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively man-aged dewatering processes typically employ continu-ous water level monitoring. Mine dewatering is usually
The KOV mine is the largest high-grade copper resource in the world. It comprises four ore bodies, Kamoto East, Oliveira, Virgule and FNSR, accessed via two pits, Kamoto East and KOV. The Kamoto East pit was operational from 1960 to 1985 and the adjacent KOV pit …
