Mechanized mining is executed by the extraction of iron ore from surface deposits. The mining areas require all the operations to be mechanized and mining is exceptionally done through systematic formation of benches by drilling and blasting. The physical processes are followed which then remove impurities and the processed ore is stockpiled ...

This chapter seeks to examine the systems of work that were used underground in two UK iron ore mining regions to present an historical perspective. Later sections will go on to contrast these mining operations with the modern deep mining techniques applied in Sweden and the huge scale surface extraction of iron ore in Western Australia and Brazil.
