01/01/2015· Iron ore was won by drilling and blasting . As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as dogger) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this
These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe.
Production drilling is carried out from production drifts at level 320 m. A standard 360 degrees fan is drilled every 3 m with hole lengths chosen to encompass the iron ore. Additional production drilling is done from level 250 m upwards to create a funnel shaped design for the lower part of the stope.

Cut and fill mining is an expensive but selective method, with the advantages of low ore loss and dilution. Drift and fill is similar to cut and fill, except that it is used in ore zones, which are wider than the method of drifting will allow to be mined. In this case, the first drift is developed in
