Mines cannot operate without a robust and flexible dewatering strategy. As no two mines are the same, each site's dewatering requirements will vary, with environmental and geological considerations as well as local climatic variations that present unique challenges. Variations in weather conditions can have a significant effect on open-pit mining in …
Dewatering is a term used in many different areas of a mining environment. In all cases, it means to remove unwanted water, but it is accomplished for different reasons and with various types of equipment. To Remove Standing Water. Dewatering can be as simple as removing standing water from a low point in the mine.
KSB's mine dewatering systems enable the safe and efficient lowering of groundwater in open pit dewatering, underground drainage and borehole drainage applications.

1.1 DESIGN OF A DEWATERING and pressure relief or groundwater control system first requires determination of the type of groundwater flow (artesian, gravity, or combined) to be expected and of the type of system that will be required. Also, a complete picture of the groundwater and the subsurface condition is necessary. Then
In addition, the smaller pipe diameter resulted in lower flow rates through the system. By sizing the pipeline correctly, you can reduce both operating costs and the time the pump needs to operate. In this mine dewatering example, proper pipeline sizing helps pump water out of the mine faster, allowing operation to return to normal more quickly.
The hydrogeologic setting in which a mine is located is a key feature in both the development of a mine plan and its successful execution. There are recent examples in Canada where difficulties in controlling groundwater inflows to underground workings led to a multi-year delay in the startup of operations at one mine and in another case …
Peripheral water wells increase a mine wall's stability by controlling water seepage. This dewatering method eliminates or limits water in some mine galleries, and drainage from galleries is cost-effective. For open pit mines. One open-pit dewatering method is to use pumps to extract water from the lowest levels of the mine.
