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 ...

BEST PRACTICES IN DRILL AND BLAST - IQPC Corporate

2017-5-9  A mine can be set up in one of two ways; either the plant is set up to accept whatever fragmentation the blasting group produces, or the plant dictates to the mining teams the fragmentation distribution they will accept. To achieve what the plant wants, electronic detonators are required. Without them, this will remain unattainable,

Our underground mines - LKAB

When blasting is complete and the blast fumes have been ventilated away, the iron ore is removed from the drifts by underground loaders, which can carry 17-30 tonnes of ore per bucketful. The ore is tipped into vertical shafts, known as ore passes. The ore falls with the aid of gravity, and is then collected in rock bins just above the main level.
