Description

Technical Field

[0002] As mining activities proceed, the discharge of mine wastewater may have a serious impact on the surrounding water environment. Mine wastewater includes pit water and mineral processing wastewater formed by mining. Most of these mine wastewaters are discharged to nearby valleys, rivers, ditches or ponds, polluting the surface water in the mining area. Since the river becomes the discharge channel for mine wastewater, the shallow groundwater on both sides of the river is polluted to varying degrees. In addition, waste residues containing harmful chemical elements pollute surface water, groundwater and cultivated land due to rainfall infiltration, causing local pathogens. The long-term stacking of waste rock, tailings and dust has been weathered and decomposed under the weathering effects of air, water, temperature, etc., prompting many harmful element compounds to enter the surface and groundwater, causing serious water environment pollution.

[0003] At present, only regular manual sampling of mine water is carried out for water environment testing, and it is impossible to obtain the overall picture of the water environment status of the entire mining area in real time, so the information cannot be managed organically and continuous water environment monitoring cannot be carried out.
