Mine water refers to all types of water that flow into underground tunnels or open-pit mines during the mining process, and is considered an unconventional water source. It mainly originates from atmospheric precipitation, surface water, groundwater, fault water, and water from mined-out areas. Based on water quality characteristics and the
1. High-Iron and Manganese Mine Water: Iron and manganese mine water in coal mines is mainly formed by the infiltration of iron and manganese-bearing groundwater from the strata. The iron and manganese in the mine water exist in the form of divalent iron or divalent manganese. Due to the effects
After prolonged filtration, a significant amount of sludge accumulates on the surface of the filter sand layer, clogging it and causing increased operating pressure, slower filtration speed, and a rising filtration level. Backwashing is then necessary. A high-volume backwash pump pumps filtered clean water into the filter from the bottom,
