Achieving Economic and Safety Benefits at the Development Face
This trial at the Newmont/Byrnecut Invicta Mine proved that the direct cost of charging development faces using emulsion was similar to that of ANFO with a comparable rate of advance, but with a lower overall total cost of advance
Application Technology - 3D Blast Modeling
The results of the HSBM 3D Blast Model analysis showed the blast pattern proposed by the DynoConsult would allow no fly to leave the blast area at this Midwest USA iron mine. Based on the results of the blast modeling the blast pattern was employed in the field. As predicted by the HSBM 3D Blast Model analysis no flyrock entered the lake and no material left the blast site.
Black Star Powers Ahead in Safety and Efficiency using Electronic Initiation
Black Star Mine moved from NONEL® pyrotechnic initiation systems to SmartShot® electronic detonators. This change eliminated unknown misfires and associated safety risks, improved the drill and blast processes, and provided complete visibility throughout the blasting cycle.
DIFFERENTIAL ENERGY® Drives Efficiencies in Australian conditions
DIFFERENTIAL ENERGY® trials in Australia have shown productivity gains of up to 30% compared to standard MPUs and products.
Differential Energy® in Surface Gold Mining
Dyno Nobel’s TITAN 1000∆E was trialed over a period of four (4) months at AngloGold Ashanti's Cripple Creek & Victor Gold Mining Co. (CC&V) in Cripple Creek, Colorado.
DIFFERENTIAL ENERGY® Technology Applied in Iron Ore Mining
Measured results confirmed that significant value in productivity, cost and blast performance were delivered. The mine reduced its overall powder factor by 18%, realized an 8% increase in shovel productivity in both waste and ore, and in the case of ore, experienced no reduction in crusher throughput. Additionally, they completely eliminated visible NOx after blast fumes in even the wettest areas of the pit.
DynoMiner® Advance Streamlines Blasting Efficiency
The Xstrata Nickel Cosmos mining operation in the North Eastern Goldfields of Western Australia is experiencing the benefits of the DynoMiner Advance first hand. Using TITAN® 7000 gassed emulsion technology, the rugged and compact DynoMiner Advance system significantly increased performance and dramatically reduced costs.
Electronic Detonator Technology Induces Breakthrough in Cave Propagation
Dyno Nobel, together with Harmony and 360 Drilling, developed an innovative drill and blast solution to promote cave propagation and improve safety. Taking into consideration the mine’s unique features, Dyno Nobel’s expertise showed how a smart design with HotShot® electronic detonators would allow the span to be increased.
Electronic Wins Blast-Off
Dyno Nobel’s trial at Sunrise Dam set out to measure the practical superiority of the HotShot® electronic detonator system over the existing NONEL® shocktube system. AngloGold Ashanti’s Engineering and Geology Department selected sites of consistent geology. The blast results were recorded using video footage, vibration monitoring throughout the mine, spot heights of muck-pile swell to provide heave profile graphs and PITRAM data.
Product Performance Verified with VOD
The customer believed the visible NOx fumes they were experience was limited to poor emulsion performance.
Redesigning Stopes for Improved Recovery of Ore
The customer was experiencing poor blast results over a substantial period of time and the under-breaking of ore left valuable material along the ribs. The mine engineers were looking for guidance on the delay times they should be using to improve the recovery of ore.
Reduced Misfires and Costs in the Cadia Hill Open Pit
Absolute control over initiation timing allowed Cadia to expand patterns and reduce powder factors by 17% without impacting mill throughput. Through clever blast design and system flexibility, Cadia was able to optimise burden relief, allowing for the best combination of blast movement, fragmentation and dig-ability.
Step Change Results in Significant Value Added Solution
Reducing slumping, NOx, and overall costs while maintaining load rates using TITAN® XL 1000 and DIFFERENTIAL ENERGY®
Using Low Density Explosives in Iron Ore Applications
Dyno Nobel developed BlastLite® and TITAN® as cost effective solutions for blasting weak to medium strength rock in Iron Ore mines. Both these products have the potential to significantly reduce powder factors and therefore, the overall cost of blasting.
