Advancing treating method for high phreatic water level coal mining subsidence area

The invention provided an advancing treating method for a high phreatic water level coal mining subsidence area. The advancing treating method is suitable for geological environment treating of a highphreatic water level mine subsidence waterlogged area. The advancing treating method comprises the following steps that mine geological mining data are collected; the earth surface subsidence condition is predicted through a probability integral predicting method, and an earth surface subsidence contour map is drawn; the 'digging deep to fill shallow' boundary is determined; the filling-digging earth volume of a 'digging deep to fill shallow' area and the final elevation of a 'digging deep' area are calculated; and according to the calculated h and the 'digging deep to fill shallow'boundary, the high phreatic water level subsidence waterlogged area is transformed, and advancing treating for the high phreatic water level coal mining subsidence area is achieved. The process is simple, the cost is low, the area 'dig
