technique of removing iron crusher ore

  • Iron ore extraction techniques ScienceDirect

      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 selfsupporting However, he states that in later years where the mining had progressed to the dip, this
