9.1 Underground Mines. Following cessation of operations, dewatering systems at an underground mine are shut down and the workings allowed to flood as the water table rises toward a new equilibrium condition. The rate at which the water level will recover depends upon the hydraulic conductivities of the subsurface geologic units and the ...

After the dewatering process is complete, the drying process can commence. Another series of cleaning pigs and soft swabs are sent through the pipeline. This is done until all standing water is removed from the pipeline. Finally, the pipeline is dried to the required dew point using oil-free compressors and desiccant dryers.

Main dewatering techniques. Construction dewatering methods refer to techniques such as wellpoints, deepwells, bypass and flood control. In wellpoint and deepwells submersible pumps are installed in a drilled well shaft, while in bypass and flood control pumps are placed in the area that needs to be dewatered. Let's review these common techniques.
