Ahead of Drill and Blast 2014, Mining IQ has assembled insights into trends, frameworks and observations that refl ect industry progress towards effi cient and productive drill and blast operations. Oversized fragments at an iron ore mine in Western Australia 1. 2. 3.
Drill & Blast Productivity Advanced blasting technology can improve the flexibility of your drilling capacity and reduce cost without compromising results or productivity. The flexibility to fire bigger blasts is invaluable to mine scheduling as it results in fewer disruptions to
Maintaining the integrity of walls is essential to the safe operation and maximise recovery of iron ore deposits. Orica’s range of solutions for wall control blasting enables steeper walls and faster vertical advance in cutbacks; reducing the stripping ratio, bringing forward revenue and increasing the project NPV. It improves productivity through:
It is well documented that drill and blast outcomes affect the downstream mining processes of loading, hauling, crushing and grinding but it can also significantly impact on mine profitability via dilution, recovery percentage, lump generation (iron ore), fines generation (coal, iron ore), coal loss and final wall stability. Drill and blast must therefore be optimised...
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.
Blasthole cone samples are used for grade control in most of the iron ore mines of the Pilbara of Western Australia. This method of sampling is straightforward when the target sampling interval matches the mining bench height but is problematic when the blasted bench is
Some 23.3 Mt of iron ore will be mined above the water table over an approximate timeframe of six years, according to a filing with the Environmental Protection Authority. MACA will carry out the drilling and blasting, and loading and hauling as part of the new pact, which is expected to generate around A$230 million ($159 million) in revenue for MACA over the 62-month term.
Apr 03, 2015· Once prepared, the mine site is cleared of ers and equipment, and the blast is detonated. Each of the holes is detonated just a millisecond apart, resulting in a pile of crude iron ore that is broken apart to a minus 2 m x 2 m size. The wide holes in the ground created by drilling, blasting, and ore removal are referred to as ‘open pits’.

equipment and drilling equipment, fragmentation tolerance, and production demands, will also influence the choice of explosives. Although a significant recurrent expense, the cost of explosives is usually only a small percentage of the total costs encountered in breaking, moving, and processing rock and ore. The small difference in the cost of a
Design of controlled blasting (pre-splitting) in Golegohar iron ore mine, Iran (S. R. Dindarloo et al.,2015). The pre-splitting holes aim to extract the rock mass in order to create a smooth face.
