Dewatering, simply means to remove water from an area. In mining, dewatering means control of inflows and lowering of groundwater levels. This usually means larger diameter boreholes around the working area.
High wall open pit mine stability is paramount in surface operations. Global Drilling Africa is an expert at improving pit operations by drilling and installing wells from the surface. This ensures pit wall stability, more effective dry blasting and blast holes, and it reduces the possibility of flooding the bottom of the pit.
