50% Blasting Cycle Efficiency Improvement
Electronic detonation has transformed production efficiency at Newcrest’s underground Cracow Mine in central Queensland.
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.
Centralised Blasting increased production by eliminating downtime before and during Blasting
BlastWeb is a centralised blasting system that is specifically designed for use in underground mining operations and allows reliable remote initiation of development, production and stope blasting from a safe and controlled location on the surface.
Centralised Blasting Systems an Approach to Safety
The implementation of Dyno Nobel's Centralised Blasting System supports both the safety of the mine employees during blasting and the elimination of misfires due to communication errors at firing time.
Development Optimisation Leads to Reduced Overbreak and Cycle Efficiencies
Various elements of drill and blast were evaluated in order to establish standards to optimise the development cycle.
Electronic Detonator Initiation System Assists with Improving Stope Productivity
Larger stopes fired with the SmartShot initiation system helps to improve productivity and reduce mine operating costs per ounce.
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 Detonators Exceed Conventional NONEL Limitations in Stopes
This mine needed an initiation system that would not restrict them from blasting a much larger stope than what they typically do, with a single hole initiation.
Electronic Detonators to Increase Underground Production Rates
Lac des Iles mine, in Canada, was wanting to expand its underground operations and increase its underground production rates.
Electronic Initiation Sparks a Surge in Safety and Efficiency at George Fisher Mine
The safety benefits realized by this mine included reduced exposure of personnel to vertical edges, less overbreak and improved post-blast ground conditions. The main production benefits were a more flexible stope design process, larger blasts resulting in more conventional dirt for the mucking units, fewer re-drills and quicker stope cycle times.
Electronics Boosts Performance Cuts Costs at the Savannah Project
The engineering team at Panoramic Resources found that with proper shot design, greatly improved fragmentation, with correspondingly less over-break, is achievable in addition to minimizing damaging ground vibration.
EZshot® Reduced Overbreak by 12% at Australian Mine
EZshot® has been rolled out across Australia in 2020 with proven reduction in overbreak, measurable reduction in volumes of material scaled off walls and initial calculations indicating positive benefits to mining costs at an Australian mine.
Improved Fragmentation Results in Higher Productivity
Dyno Nobel develops new explosive and delivery system to blast long vertical up-holes for customer.
Improved Fragmentation Results in Higher Productivity for Newcrest
When Newcrest approached Dyno Nobel with the idea of blasting a 150m long vertical up-hole, the enormity of the project was quickly realised. Conventional loading techniques and products were not suitable for such an undertaking. So a period of design and innovation ensued. During this development period, specifically designed products such as TITAN® BPC, custom made SmartShot® detonators and innovative pumping solutions were devised, put into action and rigorously tested
Improving Sublevel Caving
Dyno Nobel has modified the pre-charging practices at Ridgeway Gold Mine to deliver enhanced safety, reliability and blast outcomes.
Increasing Efficiency through Improved Shaft Cycle Times
Dyno Nobel and Burnecut-RUC-Thyssen (Telfer) Joint Venture worked together to excavate, support and line a 7.05m diameter vertical shaft to a depth of 1,100m at the Newcrest Mining Limited Telfer Project.
Increasing Tunnel Advance Rates with Dyno Nobel Initiation System
Procon Group was challenged to meet their tight tunnel advance schedule. DigiShot® electronic initiation system was found to reduce overall per meter advance with less over break, increased advance rates, and fewer booted holes to drill around.
Real Savings Delivered through Development Optimisation
With overbreak in development mining running at approximately 18% at this underground mine, improvements were required to increase the efficiency of the development cycle and reduce costs.
SmartShot and DynoConsult Expertise delivers record mass blast
SmartShot Initiation System and DynoConsult expertise delivers record mass blast for mine to transition from an open pit operation to an underground sub level cave.
SmartShot Assists with Improving Stope Productivity at Sunrise Dam
Dyno Nobel was able to provide this mine with a solution that involved the implementation of our SmartShot® electronic initiation system. Paired with our bulk emulsion TITAN® 7000, the mine had a blasting solution to help improve productivity and reduce operating costs as well as reduce the risk of misfires and provide a flexible initiation sequence with millisecond precision.
Underground Loading Process Improvement
Our evaluations of ANFO and Titan 7000 loading practices helped blaster’s visualize the inside of a horizontal development hole during loading and demonstrated best loading practices. When compared, these evaluations also demonstrated Titan 7000’s higher loading density and superior water resistance compared to ANFO.
