Whole-body Vibration Exposure of Drill Operators in Iron

These mines supply iron ore to integrated steel plants. The method of mining is top slicing with deep hole drilling and blasting. The height of the benches is 10 m in overburden and ore with bench width more than or equal to the bench height. Down-the-hole method of drilling is being practiced with 6 inch (150 mm) diameter drills.

Design of controlled blasting (pre-splitting) in Golegohar

Design of controlled blasting (pre-splitting) in Golegohar iron ore mine, Iran the model is applicable in drilling-and-blasting pattern design though it needs some calibration using the real Iron ore extraction techniques - ScienceDirectIron 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
