Groove-broaching-free sublevel filling mining method and system

The invention belongs to the technical field of slot-broaching-free sublevel filling mining, and discloses a slot-broaching-free sublevel filling mining method and a slot-broaching-free sublevel filling mining system, which are characterized in that the shrinkage rate in a filling body consolidation process and the expansion coefficient in an expansion filling body consolidation process are calculated by a method for analyzing the filling height of a filling body in filling mining; establishing a balance equation, a deformation coordination equation and a physical equation of the filling body, and comprehensively analyzing the physical performance of the filling body; meanwhile, based on elastic mechanics, in combination with a simply supported beam mechanical model, the method for analyzing the stress of the bearing layer of groove-broaching-free sublevel filling mining comprehensively considers the influence of multiple factors such as self mechanical characteristics of the bearing layer (an artificial roof
