Mining - Blasthole stoping | Britannica

Mining - Mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...
