Mine dewatering - Wikipedia

15-09-2016· Mine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine workings. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require theBlog | Mine Dewatering - Dewatering & Groundwater Control,BENEFITS OF MINE DEWATERING. Where a planned programme of mine dewatering is deployed, the mine will typically see several benefits, including: General improvement in working conditions and efficiency: better trafficking and diggability, reduced downtime due to pit flooding.Optimizing Dewatering Processes in Mining Operations,Optimizing Dewatering Processes in Mining Operations. Application. Effective water management is critical in both open-pit. and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively man- aged dewatering processes typically employ continu- ous,

Optimizing Dewatering Processes in Mining Operations

Mine dewatering opera-tions must optimize the locations and pumping rates of these dewatering wells, as well as control regional drawdown—this cannot be achieved without accurate-ly monitoring groundwater levels around the mine and surrounding areas. Depending on geologic conditions and mining practices, cones of depression (groundwa-How Dewatering Affects the Mining Process | SouthEnd,01-03-2019· Dewatering and groundwater control is so important to mining in open pits and underground. Depending on geographical location and the level of the water table in the area, dewatering the site properly can make mining a success or not dewatering can break the entire project.Dewatering Mines | Pumps & Systems,In other words, mining may move from one side of a pit because research indicates a higher molybdenum concentration exists in another ore body within the mine. As the landscape of a mine changes-whether open pit or underground-so do the requirements and space availability for mine dewatering equipment. Moving Water
