Top 10 deep open-pit mines - mining-technology

2013-9-26  The mine produced more than 100 million tonnes of iron ore in 2011. It was the maximum iron ore output by a single Chinese mine per year. A plan for starting underground mining operation at Nanfen has been underway since 2011 as maintaining the mine slope stability is becoming difficult with the gradual increase of the pit’s depth.

[PDF] Mining method selection and transition depth ...

During this paper, in order to identify the priority of consideration between the problems of “mining method selection” and “determining transition depth from open-pit to underground mining” an accurate procedure is introduced step by step. First, it is essential to specify if an ore deposit that potentially will have mined by a combined method of open-pit and underground mining.

Iron ore extraction techniques - ScienceDirect

2015-1-1  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 ...
