Drill and Blast Process In Iron Mining

An integrated approach to the drill and blast process

Aug 12, 2020· In the mining cycle, drill and blast (D&B) is arguably the first and most important step to get right. D&B operations impact the entire mining process, from mining equipment efficiency, through crushing and grinding circuit performance, to recoveries and final product quality. Costs and energy usage increase throughout the comminution process.Drilling and Blasting Technical Aspects of Mining,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.How Can Drill & Blast Operations Make Mining More,Mining is a hugely energy-intensive business. The drill and blast part of the process is very important in so far as how it influences other downstream processes. For example, the Coalition for Eco Efficient Comminution (CEEC) group of industry experts has recently compiled some thought-provoking figures.

Before the blasting takes place, the drilling rig bores the drill holes determined in advance in a blasting plan in the foremst front wall of the tunnel (working face). The more solid the rock, the more explosives are required. A jumbo is used to drill Blast Hole Drilling: The Basic Process RPM Drilling,Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.Iron Ore Mining Techniques Metal Extraction,Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
