Impact of quarry deepening on local groundwater users - SRK

The quarry depth of 78m as of 2007 caused a zone of drawdown in groundwater levels in the surrounding shale aquifer, extending ~5km to the east but a smaller distance to the west, because of good recharge from the mountainous sandstone aquifer located there. Current groundwater inflow is ~200m3/day, with an electrical conductivity of 260 to .

Groundwater flow equation - Wikipedia

the groundwater is flowing slowly (Reynolds number less than unity), and; the hydraulic conductivity (K) is an isotropic scalar. Despite these large assumptions, the groundwater flow equation does a good job of representing the distribution of heads in aquifers due to a transient distribution of sources and sinks.

    Excessive groundwater pumping can lead to groundwater depletion, and this may have serious social and economic consequences. Attempts to limit groundwater pumping have been commonly based on the concept of safe yield, defined as the attainment and maintenance of a long term balance between the annual amount of ground water withdrawn by pumping and the annual amount of recharge.

    In mining operations carried out below the water table, mine area could potentially affect the surrounding. With further deepening of the mine and quarry, the drawdown can impact on water supply wells and base flow. The variation in radius of influence under confined and unconfined aquifer condition is assessed using a hypothetical case study with three operational quarry sites.
