Iron ore extraction techniques ScienceDirect

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 self-supporting. However, he states that in later years where the mining had progressed to the dip, this

Blasthole diameter (D): Generally, the cost of drilling and blasting decreases as hole diameter increases. The relation between blasthole diameter and face height is approximately: D = 0.001 to 0.02 H Since iron ore is hard rock, and referring to Table 1 the rock factor A can be taken as 11. Assuming flyrock has to be controlled, Z=1.25.
