This method consists of blasting the ore by successive horizontal lift and extracting from the stope all the ore as the breaking occurs. The mucking of the ore is done with a scraper or loader towards a chute, generally developed in the backfill. The void then created is filled with material that can differ from one mine to the next, such as sand, gravel, ore residues. The backfill put in place serves as a floor while supporting the walls.
