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.

Mining Funda: Cut and Fill Stoping

Cut and fill stoping is a method of underground mining used in vertical stopes and in mining high-grade irregular ore bodies. The rock mass surrounding the ore deposit is also usually weak unable to support loads over an extended stoping height. As the name of the method implies, successive cutting of the ore into horizontal slices is carried ...
