Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls.

Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.

Shrinkage Stoping. In shrinkage stoping the ore is mined in successive flat or inclined slices, working upward from the level or the bottom of the block of ore. After each slice or cut, enough broken ore is drawn off from below to provide a working space between the top of the pile of broken ore and the back of the stope (fig. 88).

Shrinkage stoping is rather hard to mechanize; in addition, an important period may elapse amid the commencements of mining in the stope and the last withdrawal of all the broken ore. The solitary principal basis of tantalum mineral concentrates is the manufacture by Sons of Gwalia Ltd. from its Greenbushes and Wodgina mines in Western Australia.

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 ...

Stoping, in mining engineering, the opening of large underground rooms, or stopes, by the excavation of ore.Stoping is practiced in underground mineral mining when the surrounding rock is strong enough to permit the drilling, blasting, and removal of ore without caving.In mines where the rock requires no artificial support, the operation is known as open stoping.
