Module 1: Principles and Practical Implications
delivered by P. K. Kaiser
As mines go deeper and get larger, mine designs become more fragile largely due to the response of the rock mass to mining. Ground control and rock support become significant levers in the construction schedule, production performance, and excavation health.
This demands a shift from common to better and best practices in support design for brittle ground when displacements induced by stress-fracturing consume much of the support’s capacity.

Course Description:
This course deals with the functionality of the rock support in deforming ground. It presents an overview of guiding principles, the motivation for change, and the potential benefits for mining operations. It focuses on opportunities to overcome deficiencies in current practices and opportunities for safe and cost-effective rock support strategies. Key aspects for change management when moving toward deformation-based support design and when adopting preventive support maintenance procedures are introduced.
The course consists of three hours of presentations with active interactions presented in a virtual delivery format. As much as possible, the course material will be tailored to the needs of the participants or hosting company and the common support technologies adopted at the operations of the attendees.
VALUE PROPOSITION
The following tangible benefits can be derived from de-risking operations by a successful implementation of “deformation-based support design” principles:
Improved workplace safety through real-time monitoring of consumed support capacity
Improvement of resilience of support system through use of deformation compatibility criteria
Reduction of operation delays through minimization of severe excavation damage
Reduction of rehabilitation costs through preventive support maintenance
Optimization of ground control measures in critical infrastructure
WHO SHOULD ATTEND
The Deformation-Based Support Design for Burstprone Mines Course is appropriate for individuals who are:
Engineering Team Members involved in Mine Design
Engineering Team Members involved in Mine Planning
Senior Operations Team Members involved in the implementation of Ground Control Measures

Peter Kaiser
Prof. Peter Kaiser, Professor Emeritus, joined Laurentian University in 1987 as Professor of Mining Engineering and Chair for Rock Engineering and Ground Control at the Bharti School of Engineering. He was the Founding President of MIRARCO and later was seconded to the Centre for Excellence in Mining Innovation (CEMI) as Founding Director and then as Director of the Rio Tinto Centre for Underground Mine Construction. He is a specialist in applied research for underground mining and construction and brings extensive experience from both the industrial and academic sectors and has served as a consultant to numerous consulting engineers, mines, and public agencies. He is a Fellow of the Engineering Institute of Canada (EIC) and the Canadian Academy of Engineers. In 2013, he was awarded the Julian C. Smith Medal of the EIC for “Achievement in the Development of Canada”. He is the author of more than 350 geomechanics publications (geo-kaiser.ca). In 2019 he presented the Mueller lecture at the ISRM congress in Brazil on a topic related to this course, i.e., on moving “From common to best practices in underground rock engineering”.
Ming Cai
Prof. Ming Cai is the Geomechanics Research Chair in Laurentian University’s School of Engineering. Prior to joining Laurentian, he was a member of the Mansour Group Inc., MIRARCO, GRC, Tokyo Electric Power Services Ltd., and Tsinghua University and brings over 20 years’ research, education, and industry experience. He has a wide variety of interests in rock mechanics and rock engineering, and has made technical and scientific contributions to the advancement of rock engineering, including constitutive modeling of rock masses, rock mass characterization, rock support, interpretation of AE and microseismic monitoring data, and rock failure process simulation, etc. Dr. Cai is the author/co-author of over 200 publications. He is a recipient of the John Franklin Award in Rock Mechanics from the Canadian Geotechnical Society. Currently, he serves as an editorial board member for six international journals in the fields of rock mechanics and rock engineering.
MIRARCO—Mining, Innovation, Rehabilitation and Applied Research Corporation, founded in 1998, is a not-for-profit applied research and technical service company formed through collaboration between Laurentian University and the private and public sectors. MIRARCO serves as an innovation bridge between researchers and industry.

Canada Ontario Job Grant
What is COJG Funding?
The Canada-Ontario Job Grant (COJG) is an Ontario government funding program that offers training grants to employers. Through the program, companies may receive non-repayable funding from the government to purchase third-party business training programs, including training for in-demand skillsets. Training is expected to improve the employability and value employees can provide; including new hires in these training sessions can also maximize your funding potential.
COJG funding can reduce the cost of training employees by up to 50-83%. This can cover up to $10,000 to $15,000 in training costs per trainee.
