It also directs research in genomics the Human Genome Project originated in a DOE initiative.Wikipedia 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, lowcapacity mines have rapidly disappeared. In 2000, twelve iron ore production complexes with 12 mines, 10 concentration plants, and 10 pelletizing plants were operating in Minnesota, Michigan, and six other States.: 310KB

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.

Mar 14, 2014 0183 32Mining techniques usually consist of two types based on excavation methods. 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

Smith 1990 reported that the Cleveland deposit was associated with a very strong stone roof rock known as dogger allowing mine drivages to be selfsupporting. However, he states that in later years where the mining had progressed to the dip, this
