Abstract:In response to the engineering characteristics of the roof rock fragmentation and the stability of the stope in a mine, the three-dimensional laser detection, the selection of filling materials and the filling concentration ratio of the filling area are based on the existing mining technology conditions. The mine filling and mining method is optimized from the aspects of optimization, production and transportation of slurry, and improvement of the upward stratified filling process. Through multi-link technology update and optimization, the mine"s resource waste, property loss and safety production accidents are effectively reduced. In this paper, the filling process and materials of the stratified filling mining method are elaborated in this paper, in order to play a certain reference role for mines with similar working conditions.
