2010-6-27  Rana Gruber is an iron mine, located about 30 km east of Mo I Rana, owned by Leonard Nilsen Sons. The mine has been in activity for more than 200 years and open pit mining, sublevel stoping have been used. However, a new ore body of about 70 m wide, 1 km long and going more than 300 m deep requires a different excavation method.

Cave Mining Techniques

Cave mining techniques are the most popular methods for exploiting massive orebodies deep within the earth. In general, cave mining refers to all underground mining techniques in which the orebody is ‘undercut’ or drilled beneath the surface and is recovered as it falls. The removal of the ore causes a large gap or ‘cave’ where the orebody ...

Petra Diamonds How are diamonds mined by Petra?

In most current block caving operations, the broken ore is removed from the drawpoints by LHD vehicles, although the Kimberley Underground mines still use the more traditional gravity-based grizzly or slusher systems. From the extraction level, the ore is transported to the haulage level and out of the mine, sometimes following underground crushing.

8.4.2a Block Caving ABC 123: Testing Site / Course

8.4.2a Block Caving. This method, which was developed in the U.S. after WW I, is well suited for mining in weak orebodies. Panels or blocks of ore are undercut. Once undercut, the weak orebody begins to cave under its own weight. The caved ore is drawn off through draw points.
