This work was made possible thanks to the financial support of l’Institut de recherche RobertSauvé en santé et en sécurité du travail (IRSST). Their financial support is gratefully
acknowledged. I would like to acknowledge with many thanks the help of my research group:
Joseph Marwan, Research Associate in Mining Engineering at McGill, for his uninterrupted
devotion and hard work on this project, Wilfrid Comeau, Adjunct Professor, who was
instrumental in the design and construction of the test rig, and James Davison, Research
Assistant, who helped in many aspects of the project and notably the design and assembly of the
readout unit.
The field demonstration and validation of the SAFEBOLT technology in underground mines was
made possible thanks to the participation of Quebec underground mines, namely Bousquet,
Doyon and Niobec. In particular, I would like to thank Mr. Paul Gauthier and Mr. Alain Mercier
from the Bousquet mine, Mr. André Harvey and Mr. Robert Marchand from the Doyon mine,
and Mr. Martin Lanctôt and Mr. Steve Thivièrge from the Niobec mine. I very much appreciate
the help and cooperation of the underground operators during the field visits.
