in mining, an underground working for the collection of surface and subterranean water so that it may be pumped away. The size of the sump is based on the amount of inflow during a period of ten to 12 hours with all drainage pumps shut down. Under emergency flow conditions in a mine, use is made of the additional capacity represented by the workings lying adjacent to the sump and below the pump chamber. The sump is divided by a cofferdam into two sections; when one is in operation, the other is drained.
As places where water accumulates during drainage, sumps are used in mines, subway tunnels, quarries, and elsewhere.
