Stripping ratio

Stripping is the removal of waste rock from above and around the orebody. Stripping ratio is defined as the tonnage of waste rock to be mined, divided by the tonnage of ore to be mined from the pit. Stripping ratio is influenced by the shape of the orebody and may vary considerably during the life of the mine.

 · If a deposit was exploited by open-pit mining method, waste rocks are produced in the process of stripping. The stripping ratio impacts on the amount of waste rock greatly. According to the geometry of the orebody, different mines have a different stripping ratio and yield of waste rock.

IFRIC 20 — Stripping Costs in the Production Phase of a …

The process of removing overburden and waste materials is referred to as stripping. During the development of a mine (or, in some instances, pit; see below), before production commences, stripping costs related to a component of an orebody are capitalised as part of the cost of construction of the mine (or pit) and are subsequently amortised over the life of the mine (or pit) on a units of production basis.

Strip Mining

Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

Mining Production Activities

Pre-stripping is included in calculation of stripping ratio. Rock, both ore and waste, close to surface, may be softer than in other parts of the pit, especially if it is oxidized. Soft rock may be amenable to mining by ripping and dozing with a bulldozer instead of drilling & blasting.

Geological and Mining Consultants

 · Most open-cast mines require the removal of overburden and waste material to access the underlying orebody. This activity is known as ''stripping''. By their nature, all open pits become narrower with depth, and consequently the volume of waste to be stripped is largest on the upper benches that must be mined first. The problem is […]
