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.
