We possess that knowledge and deliver it, often teaming up with industry to conduct technical studies and offer the industry insights to significantly reduce costs and optimize processes.
Dyno Nobel Achieves Custom Blast Requirement through Blast Design
Muck from a planned shot was likely to have unwanted consequences
Evaluation of Transient Vibration
Concerns over off site impact of transient ground vibration and potential complaints associated with blasting resulted in this Mid-Atlantic Limestone customer employing Signature Hole Analysis (SHA) for determining initiation timing for all production blasts employing electronic initiation.
Focused Training Alternatives
DynoConsult’s wide range of expertise and knowledge of our customers’ needs provides the format for timely and efficient training on a wide variety of topics that can be tailored to fit site-specific needs.
Fragmentation Modeling in Underground Application
This gold mine in Canada employs long hole blast patterns in a narrow seam underground operation. Fragmentation from the blasting is always a concern as it has a major impact on the downstream processes. In addition, the fragmentation plays a role in the recovery and dilution of the ore.
Highwall Stability Improvement through Less Blast Vibration and Displacement
Highwall deterioration leads to potential hazards
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.
Improvement in Off-Site Blasting Effects
Electronic initiation systems provide accurate delay timing for today’s demanding blasting applications. Electronics also provide the explosive engineer with the ability to program precise delay times to further improve blast performance including reduced peak particle velocity and increased frequencies which minimizes ground vibration.
Is One Booster as Good as Two?
Velocity of detonation testing used to determine if one booster would work as well as two in this application.
Laser Profiling for Blast Design
To support this customer, DynoConsult provided field profiling services and data analysis for four cast blasts at this operation. Basic shot design based on 3D burden measurements was provided to the customer for final adjustments based on updated bench conditions for drilling operations.
Multiple Hole Configuration Test Shot for Optimum Firing Time and Vibration Prediction
A quarry is advancing a bench on the level 3 North Wall towards the edge of the pit and will be blasting the closest distance towards neighboring houses that the mine will get. In order to ensure vibration levels will be below the required level, a detailed Signature Hole Analysis (SHA) was performed on a series of 5 holes with different loading configurations. This will allow the mine to achieve optimum firing times while also building a database for vibration predictions site specific to approaching neighboring houses.
