Important results from the project
The goals were met at a great extent with significant contributions to existing knowledge and further improving our understanding and making new observations to further continue this project. The gas produced during the detonation in various emulsion compositions can be controlled based on different additives up to a point where plateaus appear. Regarding the water hammer effect the critical distance between the blastholes is of great importance for the safe and efficient initiation of a blast.
Expected long term effects
The long effect will be better emulsion explosives used in civil engineering and mining industry as well as the safer and more efficient tunnel blasting rounds.
Approach and implementation
The project followed strictly the planned activities, the gas measurements and the water hammer effect tests. The project on its first phase it went smoothly without any delays, however the second phase of the project had some delays due to technical issues at the testing area of the Garpenberg mine. The collaboration was as expected without any problems.
