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. Coal mines are susceptible to fume when sleeping large blasts in soft, weathered and wet sedimentary rock. In response to industry demand, Orica has developed a complete Fume Risk Reduction protocol that takes a holistic view on the blasting operation to seek and control the many possible causes of fume without affecting productivity, and in many cases without increasing costs.

Vibration and airblast control

Blasts in coal mines are typically the largest in the mining industry. Poorly designed or executed cast blasts and presplits have a high potential to generate vibration, overpressure and flyrock. Careful blast design and planning, combined with prediction, measurement and reconciliation of results is the key to controlling and managing these outcomes and maintaining a good relationship with community and regulatory stakeholders.

Dragline / dozer productivity

Achieving high productivity from large capital equipment items such as draglines depends on consistent fragmentation and muckpile presentation to reduce rehandle and unnecessary movements. By careful planning and blast design, cast to final spoil can be maximised without increasing the risk of flyrock or overpressure.

Wall control

Maintaining the integrity of walls is essential to the safe operation and maximise recovery of coal 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.

Shovel / excavator productivity

Consistently delivering high production rates enables a quarry to operate efficiently. Effective blasting can deliver consistently fragmented, loose muckpiles of the optimum profile.

Reduce drill and blast costs

Advanced blasting technology and clever blast design can improve the utilisation of the drilling fleet and reduce capital and operating costs without compromising productivity. Matching explosive energy to geology enables expanded patterns without affecting fragmentation. This in turn increases the drilling yield, providing more tonnes per drill metre. Products and procedures for safely sleeping blasts allow less frequent and larger blasts, reducing production delays and increasing blasted inventory without employing more drills or blast crew resources.

Hot and / or reactive ground

While not common, reactive ground is potentially a highly dangerous and frequently misidentified hazard. A runaway reaction between sulphide minerals and ammonium nitrate can lead to spontaneous and premature detonation of one or more blastholes at any time from a few minutes to several days after loading.

Reduced coal loss and dilution

Maximising coal recovery in challenging geologies represents a significant efficiency opportunity for most coal mining operations to increase the value of their resource. As the easy coal is mined out, mine operators need to become more skillful at mining thin, steep, deep and undulating seams productively and without sacrificing coal quality. Orica has developed significant expertise in using unconventional techniques for through-seam and deep-seam blasting and coal edge protection using our own specialist design software, geophysical tools, on-bench data management systems and electronic blasting systems.

Shovel / excavator productivity

Sophisticated mine dispatch algorithms are used to assign trucks to shovels based on predicted travel and loading times. Consistent loading times are more easily achieved when digging conditions are also consistent – meaning that fragmentation, floor levels, muckpile looseness and profile are all achieved repeatedly blast after blast.
