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.
Collaboration with DroneDeploy Leads to Mine Mapping
Most mine mapping, face profiling and volumetric analysis performed is done using reflector-less scanning laser systems or photogrammetry using calibrated 35mm digital cameras.
Controlled Blast Design in Wet or Dry Conditions
Dyno Nobel’s Z-Bar™ product has been designed as a contour charge for firing both lifter and perimeter blastholes. Prior to commercial release, Z-Bar was rigorously tested at both the Byrnecut Jundee and Placer Dome Bullant sites. At each site, a side-by-side method was used to test the performance of the Z-Bar against the existing products. Z-Bar Edge and Lifter were easier to handle and quicker to load than traditional products used. These trials achieved the project’s goals for handling and blast performance results.
Controlling Block Movement of Coal
Many mines use cast blasting to reduce the quantity of waste material handled by draglines. This technique utilizes the explosive energy to cast a portion of the overburden into the spoil pile without the need for subsequent handling. Cast blasting can also lead to an increase in blast induced coal loss unless the blast design is appropriately developed to minimize this negative impact.
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.
DIFFERENTIAL ENERGY Applied to Improve Fragmentation
Optimizing fragmentation to improve downstream operations
DIFFERENTIAL ENERGY in Iron Ore Mining
he use of Dyno Nobel’s new Differential Energy Bulk Delivery Systems technology provides large iron ore mining companies with a unique and innovative bulk emulsion loading approach, that will allow drilling pattern expansion while reducing or maintaining powder factors and explosives costs.
DIFFERENTIAL ENERGY in Metal Mine
Dyno Nobel currently supplies this metal mine market with TITAN® XL 1000. This particular mine has been successfully using this technology for over 5 years in wet hole conditions and hard rock locations while utilizing ANFO in dry softer areas of the mine. The objective of this study was to see if greater savings could be realized utilizing TITAN emulsions in all areas of the mine.
DIFFERENTIAL ENERGY in Quarry Blasting
The ground a this quarry is seamy in places creating situations where blends can migrate into the cracks. In some areas the bottom of the face contains very hard material with very soft/easy to break material in the middle of the hole. The quarry is in close proximity to neighbors so NOx and vibration are important considerations.
DIFFERENTIAL ENERGY Leads to Continuous Improvements
This mine improved safety, air quality, productivity, fragmentation and digability by using Differential Energy
DIFFERENTIAL ENERGY Technology Improves Fragmentation by 52.7%
Using an optimization study that covered a 20-month period in 2014 and 2015, the client found a high percentage of fines in the blasted stone. The client called in DynoConsult to help study the reasons and find a cost effective solution.
