Iron ore extraction techniques
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 selfsupporting. However, he states that in later years where the mining had progressed to the dip, this ...
