Mineral dewatering studies cover applications in both open and underground mines to remove ground water that will threaten the working life of the quarry from the area during the working period. Aquifer tests are performed and the impact radii are determined from the Wells; the water flow required to reduce the groundwater table to the desired level is calculated and the appropriate shots are performed. Water discharge is provided to both collection pools and existing drainage lines with the shots carried out.


From this graph showing water level change over time, hydraulic conductivity coefficient (K), storage coefficient (S) and conductivity (T) are calculated.
Pump tests give healthy results at yields above certain flow rates, while slug testing should be applied at flows below this yield, i.e. medium and low permeable aquifes.
