Advanced treatment method based on boundary optimization and for digging deep to fill shallow, and used for high-groundwater-level mining subsidence area

The invention provides an advanced treatment method based on boundary optimization and for digging deep to fill shallow, and used for a high-groundwater-level mining subsidence area. The advanced treatment method is appliable to geological environment treatment for a subsidence waterlogged area of a high-groundwater-level mining area. The advanced treatment method comprises the following steps: collecting the geological parameters of the mining area at first, and designing elevations after digging deep to fill shallow, of surface points above a main strike section of an underground mining working face; evaluating the boundary points of digging deep to fill shallow, on the main strike section, and the boundary lines of digging deep to fill shallow, for a subsidence basin according to the subsidence values of the surface points above the main strike section of the underground mining working face and the elevation values after digging deep to fill shallow; and designing an elevation of excavation and filling soi
