"deep dewatering" is correct and usable in written English.
You can use it to refer to the process of draining water from a certain area or structure. For example: "The project required deep dewatering in order to make the area safe for construction."
As mines go deeper, dewatering pumping heads become bigger, potentially involving several lift stages.
This study refers to the deep foundation pit dewatering project of Hangzhong Road station of Shanghai Metro Line No.10.
Dewatering deep hole excavations in aging quarries leaves mining engineers with few portable pumping options, none of them good.
In order to control the land subsidence effectively, the underground continuous concrete wall is often used in the deep foundation pit dewatering.
For deep foundation pit dewatering in the Yangtze River Delta, it is easy to make a dramatic decrease of the underground water level surrounding the dewatering area and cause land subsidence and geologic disasters.
Accordingly, the three-dimensional finite element numerical simulation is the basic theory of optimization design of engineering structures of dewatering in deep foundation pit in such areas.
Artificial recharge measures have been adopted to control the drawdown of confined aquifers and the ground subsidence caused by dewatering during deep excavation in Tianjin, Shanghai and other regions in China.
Deep Sea Mining — Prof. Peacock recently participated in the Ventbase 2016 June meeting in the Azores with a view to developing protocols for limiting the environmental impact of dewatering plumes generated by deep-sea mining activities.
