At the end of an open pit operation, sump pumps and/or dewatering wells are decommissioned. The geometry of the pit and the void volume may be modified if partially backfilled with mine waste. Following cessation of pumping, in most climatic regimes, both surface water and groundwater will inflow to the pit, creating a pit lake (Figure 19). These pit lakes become part …

715· When excavation for mining limestone extends above the ground, it is called opencast mining, and when extended below the ground, it is called open-pit mining. The opencast mining of hill deposit formations has further classification in terms of mine benching and stripping, whereas for open-pit mines, only the benching system is applicable.
