ABSTRACT
EPC Groupe (French explosives manufacturer for 125 years) has developed a new monitoring software for qualifying, and then, improving quality and efficiency of drilling and blasting jobs in tunneling works. Everybody knows that in tunnels built with Drill & Blast method, everything starts with a good quality of drilling and then blasting. If these two first tasks are not well done or controlled, the downstream operations will be impacted with low efficiency and then over costs. One of the great difficulty is to get all informations (advance, over and under breaks, fragmentation, and all KPI’s linked to the downstream operations) into one tools in order to have a quick overview of the quality of D&B works, and then, correct as soon as possible, leverages on the drilling pattern, blast pattern and/or timing sequence. With the help of modern tools (using of digital tools for measuring many parameters), and the help of photogrammetry (using simply the camera of a smartphone), it could be easier to get in one box, all information’s related to D&B efficiency linked to downstream operation measured with KPI’s. This paper presents the tools, and how it is used to qualify the quality of D&B operations in different audits driven in UG mines and tunnels works.
