Where ground conditions permit, it is possible to use a combination of cutandfill mining and sublevel stoping called rill mining. In this method drifts are driven in the ore separated by a slice of ore two or three normal slices high.
The invention discloses a sublevel shrinkage caving stage open afterwards filling mining method. In the earlier stage of stoping, caved ores are utilized to support surrounding rocks on a top tray, and in the later stage of stoping, a goaf area is filled with fillers to control ground pressure so as to achieve safe and efficient mining.
