Stoping mining Britannica

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.

The Stoping Method Mineral Production Activities

The stoping method used in a U/G mine is also referred to as the mining method, even though stoping is only one part of the mining process. It is the phase which yields most of the ore produced. Selection of stoping method is one of the most important parts of U/G mine design and is influenced by: Dimensions (size & shape) of the orebody

Shrinkage Stope Mining, Mining Methods, Mining Techniques

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.
