Abstract: Through comprehensive analysis and research,it is considered that groundwater can be used in initial water supply for coal mine development,with a water supply capacity of 6×10⁴~7×10⁴ m³/d.Groundwater in Quaternery Salawusu Formation and Luohe Formation around the coal mine can be selected for middle-long-term water-supply.Meanwhile,coal mine water can supply groundwater by means of filtration,richen groundwater resource,to assure water supply for development in the mining area and environment protection.
