IQ Scottish Branch - Advances in Blast Design
DescriptionIn recent years there have been significant advances in our understanding of rock mechanics, blast mechanics, ground motion and digital engineering. Despite these developments applying this knowledge to improve blast design and reduce full life cycle costs has remained a complex and largely unattainable task within the quarrying industry. With the application of machine learning and expert understanding of the interplay between the aforementioned complex fields we can now take advantage of new techniques to optimise blast design and reduce production costs. With this enhanced insight we are now better positioned to start challenging increasingly onerous and often misguided ground vibration restrictions imposed upon the industry. The presentation will commence with a critical review of the current vibration damage standards and questions the validity of the industry’s current approach to ground vibration prediction and control. We then discuss the latest theories of blast mechanics presented through a stress-strain analysis. The presentation will then conclude with how these advancements are being applied to fragmentation optimisation coupled with a full life cost model in a newly developed Mine to Mill system.
