Selection the most favorable pump type and configuration of pump systems at the open pit Gračanica - Gacko

Abstract

Coal mining at the OP Gacko - Central Field takes place on two spatially separated locations: the Central and Overlaying exploitation zone. The deposit Gacko has a high coefficient of watering due to the large catchment areas, high values of maximum rainfall and presence of aquafers, as well as the continuing flow from the existing water flows and channels. Due to these reasons, a correct selection and sizing the structures of water protection system are very important from the techno-economic aspects.
