In order to identify the most economic and low cost method, it is very essential to identify the source of groundwater seepage.
The successes of dewatering operation depend on the understanding of the local and regional groundwater regime.
The results of the study can be used to plan optimal groundwater pumping and the possible locations to dewater the groundwater for safe mining at different mine development stages..
If the host rock is significantly permeable, it can become a big problem for the excavation operations.
The estimation of inflows coupled with structural mapping of the geology gives very valuable information to determine and control the volume and occurrence of groundwater inflows.
The flow model was calibrated under steady state conditions and predicted groundwater inflows into the mine pits at different mine development stages.
The groundwater budget results revealed that the mining area would receive net groundwater inflows of 5877 m at six mine development stages of +124 m (amsl), +93 m (amsl), +64 m (amsl), +41 m (amsl), +0 m (amsl) and −41 m (amsl), respectively.
Dry working conditions are preferable as they reduce wear and tear of machinery, reduce earth moving costs that improve the slope stability and therefore safety can be assured in mining operations.There are number of methods available for the mine management and they are dewatering, diversion, sealing or a combination of these methods.
