Control of groundwater in surface mining - Mine Water
The presence of groundwater in surface mining operations often creates serious problems. The most important is generally a reduction in stability of the pit slopes. This is caused by pore water pressures and hydrodynamic shock due to blasting which reduce the shear strength and seepage pressures, water in tension cracks and increased unit weight which increase the shear stress. Groundwater and ...

A Simple Approach to Managing Dewatering in an Open
Once a mine is operational and dewatering has commenced, the major issue is making sure the dewatering keeps up with the mine plan. This can be achieved using analytical element modelling. The dewatering approach for mine deposits is to maintain groundwater levels below the pit floor in advance of mining and throughout the life of mine operations.
