Sublevel caving techniqueSimplicity and low costare the essence controlled drilling and blasting.Sublevel cavingis in many respects simple. It can be used in orebodies with very different properties and it is easy to mechanize. Insublevel caving, ore is developed from a series of sublevels spaced at regular intervals throughout the orebody.

    Sub level caving method allows working in parallel on different sub levels in the mine. This means that continuous excavation works can be on-going at one sub level without interfering with another. Project Sublevel Caving was carried out during the years 2009 and 2011, with a budget on 450 million NOK.

    Sub-level caving. This method owes the first part of its name to the fact that work is carried out on intermediate levels (that is,sub-levels) between the main production levels. It follows the same basic principles as the blockcaving miningmethod, but the caves are smaller in size and not as long lasting.
