Study on mechanisms of treating mine wastewater by goaf and the methods of recycling mine wastewater in Jining No.2 coal mine
Suspended solids are major pollutants of mine wastewater that can be recycled by flocculating, settling, and filtering for domestic and industrial use. For a long time, only a few collieries have adopted traditional technology to dispose of and recycle mine wastewater because of high cost. Most of mine wastewater is directly discharged, which not only contaminates the environment but also wastes precious water resource. So it is of great importance to explore new efficient treatment methods with low cost. Goaf which is full of broken stones has many interstices with different sizes suitable for filtering and purifying wastewater. Through model goaf, this paper mainly deals with the methods and mechanisms of wastewater treatment by goaf under coal mines. According to the characteristics of different goaf of Jining No.2 mine, we choose the best disposal scheme. Treating wastewater by goaf can utilize the mine wastewater effectively and economically.
