Sublevel open stoping. From QueensMineDesignWiki. Jump to: ... For sublevel stopping most drill patterns involve keeping the holes on a vertical or near vertical plane on each sublevel. The length of the hole to be drilled depends on the extent of the ore and the sublevel spacing. ... Sublevel open stoping is a highly mechanized mining method ...
It is therefore the best method to turn a carefully planned drill and blast design into reality. No need for undercuts . When conventional drilling methods are used for sublevel stoping, with long distances between the levels, it is common to drill an undercut to avoid the risk of high blast hole deviation.

In any discussion of Methods of Underground Mining Comparison, one is repeatedly confronted with the difficulty of dealing with so many variable conditions. It is not an exact science and in the choice of a method each varying factor has a certain weight, which, in many cases, experience alone can determine.
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal ...

This method has the advantage of giving geological and geotechnical teams further analysis of the stoping block prior to mining. Boxhole boring, similar to raise boring but less productive as broken material is extracted from the same location as the drill, is used to bore vertically with no top level access required.(hamza,2016) References
We use this for mining platinum. Large scale mechanised mining methods we use include: longwall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sublevelcaving, where levels of the ore are blasted by explosives; and

Cutandfill stoping is applicable to the mining of firm ore enclosed within walls, one or both of which are weak and heavy. The deposits may be tabular in form, dipping at angles steeper than the angle of repose of the broken ore (or flatter, if scrapers are employed for moving the ore in the ore passes), or to wide, thick ore bodies or masses.
The method may be used for ore mining in shrinkage stopes, for rising, and for underground construction projects where excavations of considerable vertical height may be needed, like ore and waste bins, crusher rooms, penstocks and tailrace tunnels. ... and the level of the broken material in the excavation. This is attained by drawing the ...
