Drilling in the benches of open pit mining is done for production of iron ore with mechanized drills specific for each mining method The main objective of drilling operations is to create a hole of suitable diameter depth and direction in rock for explosives to be placed for blasting activitiMining Iron Ore Mining iron ore begins at ground level Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth Taconite rock comprises about 28 percent iron the rest is sand or silica These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan

Mining Mining Underground mining When any ore body lies a considerable distance below the surface the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive and underground techniques must be considered Counting against underground mining are the costs which for each ton of material mined are much higher underground than on the Underground mining is practical when The ore body is too deep to mine profitably by open pit The grades or quality of the orebody are high enough to cover costs Underground mining has a lower ground footprint than open pit mining The underground mining methods we use include room and pillar narrow vein stoping and large scale mechanised

Diamond drilling or core drilling this is the ideal method for most exploration but is generally about three times the cost of RC per meter The phrase diamond drilling refers to the drill bit which is studded with industrial diamonds in a metal matrix it produces a core of solid rock which provides much more geological information than RC chipsApr 09 32 Exploitation of existing iron ore deposit is the easier part of the mining operations The harder part is to find new ore deposits and to define their extent and the iron content grade Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust
