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. Benefits of using MDX:
Iron Ore; Iron Ore Fume Risk Reduction. Fume Risk Reduction. The generation of nitrogen oxides within post-blast gases (commonly referred to as “fume”) has become increasingly important for mines from a safety, productivity and regulatory standpoint, particularly those in populated areas. In response to industry demand, Orica has developed a complete Fume Risk Reduction protocol that takes

Mining 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.

The project, some 33 km south of Marble Bar in the Pilbara, will see Atlas develop five open pits using conventional drill and blast, and load and haul methods. 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
Failure to accurately account for blast movement results in ore loss, dilution, or misclassification (low grade to high grade ore, sulfide to oxide, or other contaminates). The financial consequence of getting this wrong is significant and diminishes the geological QA/QC done in defining the ore body. Cowal gold mine increased mill feed grade by 7% through blast movement monitoring. The main
A rotary air blast (RAB) drill has arrived on site to investigate historical and newly mapped regional copper showings, as well as recently developed geophysical targets buried by overburden to
Drill and blast teams face myriad challenges associated with drilling route allocation, operational loss through rough estimations of drilling length, load design, reporting and control.
Drilling and blasting cost in any project can be as high as 25% of the total production cost. Inspite of this the design and implementation of a blast is not given that much priority in our country. Proper adoption of drilling and blasting can contribute significantly towards

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 ‘flitch’ mined in two or more passes. Crucially, the sampler needs to decide which part of the blast cone represents the
Iron ore of merchantable grade must be properly sized prior to charging to the blast furnace. Present blast furnace technology commonly requires crushing and screening of direct charge lump ore finer than 10 mm and coarser than 30 mm. The specific size selected is based on the characteristics of the ore and is specified so as to maintain high stack permeability and also allow sufficient time

Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation.It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction.The result of rock blasting is often known as a rock cut.. Drilling and blasting currently utilizes many different varieties of
For one of the wireless blasts, a stope would not be accessible after the first blast, but, as the stope could be pre-loaded with wireless detonators, the mine could blast and produce 4,000 t of extra ore that otherwise would have been sterilised.

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...

The 20-strong fleet will initially be controlled at BHP’s five iron ore mines in Pilbara, with the longer term aim of remote operation from a base in Perth. The transition to automated operations isn’t always seamless, however. Software issues delayed Rio Tinto’s planned roll-out of autonomous trains in Pilbara, reducing the multinational’s iron ore output in Pilbara in 2016 by 20
