  • underground coal mines dewatering systems

    Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a prerequisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts.

    SYSTEM FOR UNDERGROUND MINES DEWATERING Generally, water presence in the floor sandy partings is one of limiting factors in the mining process, due to hydrostatic pressure as well as high prices of water withdrawal. From the aspect of dewatering and safety at work, each locality or technology has its own specific features and requests. Therefore, the selection of methods and

    When planning and operating their mines they must factor in the potential impacts of dewatering on the baseflow of rivers, springs, wetlands and other groundwater-dependent ecosystems. Extracted water which is surplus to mining requirements must also be carefully managed. This means looking much further than the visible footprint of the mine site and gaining greater insights into the surrounding
