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.

Iron is produced from iron ore.Ores carrying higher quantity of hematite or magnetite are called natural ore and can be directly fed into blast furnace for the extraction of iron.In iron ore mining process, rocks carrying high quantity of ore are identified, followed by drilling blast holes in the rocks.

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
