Productivity and Cost Control
On the following pages, you will find real-world success stories where our industry experts have worked with our customers to deliver groundbreaking performance. Simple or complex, Dyno Nobel’s experienced people and specialized services can solve your blasting challenges.
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.
Fines Reduction Project at Wendling Bowser Quarry
The goal of the study was to achieve the best possible fragmentation with chemical blasting for costs and for bank ton yield from reduced fines. Customer had attended Quarry Academy and saw opportunity for applying principals discussed at QA to improve his operation and reduce costs.
Fragmentation Modeling in Underground Application
The fragmentation model produced by DynoConsult for this platinum mine in the Western United States showed a matrix of various hole diameters, burdens and spacing and the expected fragmentation results. This matrix allowed the operation to determine which parameters will best achieve the desired downstream results.
Higher Powder Factor Increases Crusher Throughput and Digability Rates
Unacceptable dig rates and crusher throughput prompted this mine to increase product density.
HotShot 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.
How Dyno Nobel Reduced $40 per Tonne on Explosive Costs
Dyno Nobel has been an industry leader in introducing technology that utilizes mine waste oil in blasting agents. Our customers have realized substantial savings achieved through the direct replacement of 50% of the fuel (DFO) cost for blasting. In addition, the technology has delivered further cost and environmental gains to our customers through the elimination of storing, handling or shipping used oil to a third party for re-refining or disposal
Improved Digability, Reduced Vibration in Truck Shovel Operation
Reduced vibration allows mine to disregard scaled distance limitations.
Improved Digability, Reducued Vibration in Truck Shovel Operation
The close proximity of both power lines and railroad tracks caused this mine to adopt blast designs that did not result in optimum digging rates for shovels. Use of scaled distance calculations required multiple decking that did nothing to aid in digability while having marginal impact on vibration at key structures. The use of SHA (Signature Hole Analysis) and electronic detonators allowed the mine to dial in optimum timing sequences regardless of the number of holes per delay, resulting in reduced vibration and better digging rates allowing for faster removal of overburden.
Improved Fragmentation and Digging Results
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.
Improved Fragmentation for Road Development
This mine needed increased fragmentation in the blasts to build up smoother roads with less oversize.
