In the mining industry, in-depth knowledge is crucial for driving and sustaining change that results in improved productivity. 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.
Adjusting Design for Plant Facing Shot
This limestone quarry in the Eastern U.S. has been using an internal pattern of 16 x 18 feet with an inverted pattern of 18 x 16 feet on the front row. This quarry has many neighbors located around it and the plant and mine structures are located close to the pit. Fragmentation and vibration have been the key points to this quarry.
Angled Holes Used to Blast Excess Burden
Evaluation needed for appropriate burden on angled holes
Boretrak Used for Appropriate Loading of Shot
Multiple blasters create challenges
Boretrak Used to Detect Hole Deviation and Toe Burden
DynoConsult was called in to help reduce coal loss from blasting and determining why there were inconsistent results of face movement. There are several factors that can contribute to this problem. Some may not have an easy solution, but could be minimized by determining some of the dimensions that are taken for granted, such as face burden and borehole deviation.
Comparison of Fragmentation Results by Varying Time Between Top and Bottom Primers
Study conducted to find optimal delay timing for this granite quarry
DYNO 42™ Used for Vibration Control
DYNO 42 used to pinpoint best delay sequence for vibration reduction.
Dyno Nobel Achieves Custom Blast Requirement through Blast Design
Muck from a planned shot was likely to have unwanted consequences
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.
Highwall Stability Improvement through Less Blast Vibration and Displacement
Highwall deterioration leads to potential hazards
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.
