What is the depression of the water table in the areas of the Open Pit and Underground mining pits? At MDH we have extensive experience drilling and instrumenting water wells of different diameters 6″, 8″, 10″ and 12″. We have our SCHRAMM TW685 equipment to drill water wells with diameters from 8 to 24 inches. , with the use of tricone drill bits and large diameter reamers, using the flooded well system with the use of mud and additives. In order to provide greater guarantee of the flow found in a water well, we provide the pumping testing service and the files until the approval of water use by the ANA (National Water Authority).
