10/12/2016· The process of developing an iron ore mine from exploration data through to 14 May 2014 drilling and blasting for iron ore More details: drilling and blasting iron ore mineDrilling and Blasting | Technical Aspects of Mining,,Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions. Hand-drilled holes seldom exceed 400mm in,Mining of Iron Ores – IspatGuru,14/03/2014· 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 activities. The drilling of the holes is done normally in a particular pattern which depends on the bench,
