Dave Mackintosh has just passed 50 years in the potash mining industry where he started as a rock mechanics technician in 1969 for Cominco (Agrium, now Nutrien). His supervisor at the time was Jim Popowich, past president of CIM. He remained as a technician for a number of years, and became a local authority. He finally finished his geology degree at the University of Saskatchewan in 1985, and after 26 years with Cominco, formed ADM Consulting Limited in 1996. Since then, he has been fortunate to work on projects in Thailand, Europe, Britain and throughout North and South America.

He currently oversees the ground control programs for the Fraser Mine Complex and Nickel Rim South Mine, is the lead for the future mines of Onaping Depth and Nickel Rim South Extension, and is a member of the Workplace Safety North Ground Control Committee. He has also worked in ground control in Canada for Craig and Onaping Mines, Noranda Technology Centre, and Brunswick Mine. In South Africa, he worked at President Steyn Mine. Brad is an exceptional engineer who has written numerous papers on the practical application of rock mechanics principles in operating mines. Brad's knowledge, guidance, understanding, and recommendations have been helping people in underground jobs come home safely. He realizes that it is important for mining companies to investigate and document new methods and technologies for the next generation, with the hope that they will be able to further advance the field of rock mechanics.
