Cut and fill stoping is applicable to the mining of firm ore enclosed within walls, one or both of which are weak and heavy The deposits may be tabular in form, dipping at angles steeper than the angle of repose of the broken ore (or flatter, if scrapers are employed for moving the ore in the ore passes), or to wide, thick ore bodies or mass.
Cut and fill Mining Description In cut and fill mining the ore is excavated by drilling and blasting in horizontal slices, starting from the bottom of a stope and advancing upwards as in shrinkage stoping A slice has a thickness of not more than 3m The broken ore is loaded and completely removed from the stope When one slice of ore has been excavated, the corresponding volume is filled.
