·Image Credit Adwo/ Reverse circulation RC drilling has become standard practice in most mines across the world First developed in Australia in the 1970s the drilling technique was originally conceived as a solution to the drilling difficulties encountered when using open hole techniques in soft iron ore and mineral sands
·Blast furnace A large structure in which iron ore is smelted into iron metal Blasthole A hole drilled for the purpose of blasting rather than for exploration or geological information Blister copper A crude form of copper assaying about 99% produced in a smelter that requires further refining before being used for industrial purposes
The azimuth is just a direction to turn the rig Someone will set up foresights or backsights or both so the driller can line up the drill rig to They then elevate the drill head so that the drill is angled at the correct Dip This is the angle down from the surface the drill is drilling
