Project description
The overall objective of the project is to increase the level of understanding of the link between mining seismicity and the evolution of the stress field within the rock masses subjected to mining. It is known, from laboratory experiments, that stress changes in a rockmass influence the propagation speed of seismic waves. The study of changes in seismic velocity thus makes it possible to infer the stress state. In situ mapping of speed changes is possible through the use of seismic monitoring networks typically used in mines. The INRS team previously developed a method that can track velocity variations in real-time from seismic records, but this method needs to be validated with substantial datasets that will allow its robustness to be assessed. One of the specific objectives of this project is to conduct this validation using datasets from two separate mines. The application of the methodology with these datasets will ultimately improve our understanding of the impact of an exploitation sequence on stress redistribution and the resulting seismicity. A second specific objective of the project is to optimize and accelerate the methodology by incorporating recent computational methods based on deep learning.

Equity, diversity and inclusion
Professor Giroux adheres to the principles of equity, diversity and inclusion in the recruitment and training of highly qualified personnel. Applications from groups that are underrepresented in the academic research community in the field of science and engineering are strongly encouraged. With equal competence and level of experience, the advantage will be given to the candidate from an under-represented group.
