Iron ore extraction techniques - ScienceDirect

2015/01/01· Initial mining at Kiruna took the form of opencast methods, and for 65 years, all the ore was mined by surface methods to a depth of 275 m. Thereafter, mining was concentrated at the underground mine that began production in 1957 ( Chadwick, 2010 ).

Method for mining of rock or ore according to the block caving

A method for mining of rock or ore according to the block caving principle, comprising driving, at several levels, substantially straight, parallel and horizontal drifts into the lower part of a block, choosing the distance between the drifts of each level so that remaining supporting pillars will cover at least 40% of the block area, undercutting the block from the drifts from opposite sides of the block so that the drift

Underground Mining Methods — New Pacific Metals

2018/02/26· Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
