Mining Method Stopping

Stoping - Wikipedia

Long hole stoping as the name suggests uses holes drilled by a production drill to a predetermined pattern as designed by a mining engineer. Long hole stoping is a highly selective and productive method of mining and can cater for varying ore thicknesses and dips (0 - 90 degree). It differs from manual methods such as timbered and shrinkage as once the stope has begun blasting phase it cannot be accessed by personnel. For this reason the blasted rock is designed to fall into a supported drawpoint o…

Stoping Mining Methods - Metallurgist & Mineral …

Stoping Methods. A classification of stoping methods based upon method of support was adopted by the Mining Division of the Bureau of Mines in 1928. This classification has been used ever since as a basis for describing methods in its publications dealing with mining methods and costs and is as follows: Classification of stoping methods

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.
