Edumine | Design and Application of Sublevel Stoping Methods

 · Variations of this method include vein (Alimak) mining, transverse stoping, Avoca and longitudinal mining. Sublevel stoping accounts for more than 60% of all underground production in North America. This is largely due to the developments of extension steels, hollow tube and special long-hole rock drills, and ITH drilling techniques requiring less development and greater production capacities.

Stoping

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.[1] 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. The earliest forms of stoping were conducted ...

METHODS IN MINING BY SUBLEVEL CAVING

Applications of the sublevel caving hitherto used in mining have all had the same disadvantage in common with most other mining methods, viz. the difficulties to provide an acceptable ventilation. Usually the loading drifts have been put under negative pressure or suction and consequently via the caved materials sucked up fresh air coming from ventilation shafts or headings.
