Mining of Iron Ores – IspatGuru

The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.

A Underground Method of Mining Iron Ore

Some ore deposits found in jasper-slates and in the horizon between these and their associated clay-slates; in the latter they are true contact-deposits. They are found in this jasper- and clay-slate formation under varied conditions, yet, in all, certain characteristic laws are preserved. The angle of dip varies from 15° to 20°, and up to 85° and even 90°, with the horizon. The ore is ...

Mining - LKAB

Underground mining. Ore is extracted from LKAB's underground mines by means of sub-level caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader.
