Mitigation
Recharge of pumped water back to the aquifer, grout curtains around the workings, and allocation limits set from a monitored regional model rather than the mine's own balance.
Mechanism
A pit or shaft below the water table only stays dry if it is pumped, and pumping lowers the water table across a radius far wider than the hole. Wells, springs and wetlands that depended on that level fall with it, and in arid districts the mine competes directly with everything else drawing on the aquifer.
