Our underground mines - LKAB

In order to mine iron ore underground, we have to build transport routes in the rock, i.e. tunnels known as drifts. Development consequently entails making preparations for mining. A development drift is blasted directly through the ore body and, if necessary, the walls and roof are reinforced with bolts, mesh and sprayed concrete.


A residue storage facility (RSF) was designed to cater for Davidson Creek Area and Robertson Range Area operations under the FerrAus Pilbara iron ore development project in the Pilbara Region, Western Australia. Annual ore production was about 15 million tonnes over a period of up to 15 years. The RSF was designed to handle a tailings production rate of 2.2 Mt/a over the …


ore quantity refers to the ore quantity to be extracted ac-cording to the design in the balance sheet; its loss rate is one of the important indicators to reflect mining and technical management level. Ore grade reduce due to mixture of waste ore and loss of rich ore powder during the mining process is called dilution.
