We would like to thank all the authors from around the world who took the time to submit abstracts and papers for the 50th Annual ISEE Conference. We would also like to thank our reviewers who worked hard to review all the papers that were submitted. It was a rigorous peer review process with over 145 abstracts and papers reviewed by 27 dedicated reviewers across 4 continents. This resulted in 65 papers being chosen for presentation.
We are pleased to announce the Top 2 Papers by merit:
1st: Nathan Skopak (primary author) - Use of a Scaled Concrete Model to Determine the Origins of Air Overpressure.
Summary: Determining the origins of air overpressure has been a long-debated topic within the explosives engineering community. Significant research has indicated that the time at which the air overpressure pulse exits the face fails to coincide with either the arrival of the shockwave at the free face or the initial face movement. Therefore, to best determine which blast mechanism contributed to the initial air overpressure pulse, testing was aimed at verifying the precise time at which the air overpressure exited the faces compared to when the face first moved. This research describes tests using scaled concrete blocks, which provided the ability to control the key parameters necessary for the research to be successfully concluded.
2nd. Tristan Worsey (primary author) - Worsey-Silva Equation for Modeling Fragmentation Caused by Row Timing
Summary - The Worsey-Silva equation determines the optimal row timing for the smallest fragmentation and allows fragmentation models to be adjusted due to row timing. The equation utilizes the concept of dynamic confinement to determine when the best time to fire the next row or sequence series would be if the smallest fragmentation is desired. Full-scale testing was conducted at an aggregate quarry in Ontario to support the theory and equation. The paper explains the theory behind the equation, the research supporting the findings, and the developed Worsey-Silva equation for row timing.
Congratulations to both Nathan and Tristan who will be recognized at the ISEE conference in Savannah, Georgia, USA!
