Coal mining method for controlling surface subsidence by floor isolation grouting and filling

The present application relates to the field of mining area subsidence reduction and filling mining, in particular to a floor isolation grouting filling control surface subsidence mining method; a certain thickness of rock stratum is selected as a floor pressure bearing protective layer below a floor failure zone, the floor pressure bearing protective layer arches under grouting pressure, but no fissure leading to the upper floor failure zone is generated; the floor pressure bearing protective layer bottom interface is taken as a grouting layer, a grouting borehole is connected to the grouting layer; working face mining is carried out, when grouting filling can be carried out, filling slurry is injected from the grouting borehole to the grouting layer. The filling slurry lifts the floor grouting pressure bearing layer and the floor failure zone under high pressure, finally fills the entire goaf, reduces the breaking degree of the coal seam roof, controls the subsidence amplitude of the overlying strata, and further reduces the surface subsidence amplitude. In the present application, the mining and grouting filling processes are separated, the influence of grouting filling operation on working face mining is avoided, and the present application is particularly suitable for coal mine areas with dense buildings.
