The real-time method currently used for iron ore classification is manual inspection of drill chips and core on-site by a trained geologist. This method however is highly subjective and grade estimation is only about 35% correct (pers. communication and pers. experience within the iron ore industry).

The central proposal of our work is the development of this detection of the risk of collapse of iron ore based on its image. Red carried iron ore with risk of avalanche has a brighter image, while material without risk tends to be more opaque; these are the main characteristics that allow the differentiation between the types of material and its …

Iron ore was won by drilling and blasting (Figure 7.1).As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be self-supporting. However, he states …

Mineralogical characterization helps in identifying the mineral distribution in the ore sample and provides the textural information, in turn assisting in determining the grade of iron ore by describing the modal distribution of both the ore as well as the gangue minerals. It also pro-vides information essential for the downstream processings.
