文摘
Groundwater impacts of UPSH in an old mine are studied by groundwater modelling. Head oscillation in the mine is transmitted in the aquifer. Mean head in the mine is lowered creating drawdown in the surrounding. Seepage occurs from the aquifer into the mine. Impacts vary with permeability values, pumping/injection rates and schedules.
