iron ore surface mining facility
Energy and Environmental Profile of the U.S. Mining Industry 4
4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.

Iron ore extraction techniques - ScienceDirect
Jan 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 ...
