Blast Fume Reduction - New Acland Coal Mine Queensland, Australia
16/06/2015

New Hope Group’s New Acland Coal (NAC) site is a multi-pit, open-cut coal mine situated approximately 150 km west of Brisbane in Queensland. The NAC site produces 4.8 Mtpa of coal for export and local markets. Bound by rural properties, the New Hope Group is committed to being a responsible organisation towards both the environment and the local community in which it operates.

The challenging geology of the area is prone to the production of post blast emissions in the form of oxides of nitrogen (NOx). NAC is strongly committed to high environmental and community standards and made the decision to concentrate on a NOx elimination / minimization process.

Orica commenced blasting services at NAC in January 2013 with the agreement centered around Key Performance Indicators (KPI) for services and bulk explosives that are specifically geared toward the reduction of NOx fume events.

Managing blast vibration whilst increasing tunnel advance rates

Toyota City is located in north-central Aichi Prefecture, Japan.
With some low lying areas of Toyota City prone to flooding, Kajima Corporation were contracted to excavate the Anei River tunnel to increase drainage capacity. With granite rock too hard for excavation, blasting was the obvious solution however, the tunnel ran directly beneath a residential area.
Orica proposed the use of the eDev™ II Electronic Blasting System combined with Orica’s SHOTPlus™ T software for design, modelling and vibration analysis. The Multi Deck Blasting technique was also used to allow Kajima to blast through the most sensitive areas of the project with half the amount of blasts that might have been required using the conventional blasting technique, minimizing delays to both neighbors and construction activities, wiping months off the project’s critical path.

Reduction in total blasting cost of mine using Electronic Detonators

From the days when plain detonators and safety fuse were used for initiation of commercial explosives, the commercial blasting and mining industries have made rapid strides.
With the advent of electronic detonators in the late 90s, the face of commercial blasting was forever. The Indian mining industry initially took a while to embrace Electronic Blasting Systems (EBS) however, more recently the industry has taken to EBS in a big way.

Though electronic detonators have grown in prominence in India in the last decade; their use has been restricted mainly to environmental control. With increased knowledge and understanding of the recent developments in blasting around the world, EBS in India has now started being perceived as a tool to improve productivity and reduce cost.

Cost, productivity optimisation through blast planning, scheduling
23/01/2015

An optimised blast plan developed between one of Australia’s largest aggregate companies Boral and Orica at a Queensland quarry has delivered significant improvements to the operation’s annual extraction plan. Karen Normanton outlines how the two parties were able
to optimise blast performance, improve size and shape and reduce costs per tonne of rock.

The Enhanced Borehole Camera (EBC mkIII) combines a number of capabilities from other
instruments into one unit. The unit is capable of measuring depth, hole diameter, and hole temperature
at the same time as recording video footage. Postprocessing allows this data to be combined to produce
a final video with the telemetry synched to the video footage.
