CIM CONNECT CONVENTION 2025
AMC Consultants is proud to exhibit and present at the CIM Connect Convention + Expo 2025, taking place at the Palais des Congrès de Montréal between 4 May to 7 May, 2025 in Montréal, Canada.
As a leading global mining consultancy, AMC is dedicated to advancing best practices across the minerals, metals, materials, and energy sectors in Canada.
We look forward to connecting with industry leaders and professionals at this premier event to share insights, foster collaboration, and help shape the future of mining.
Visit us at Booth 824
We invite attendees to visit
Booth 824 to connect with our team and learn more about how AMC Consultants deliver world-class solutions for underground mining operations.
This year’s Convention + Expo will showcase the latest advancements in mining technology, solutions, and services. The 2025 theme,
“Minerals, Innovation and the Energy Transition,” will frame key discussions around:
- Mining extraction processes
- Economic value of the minerals
- Tailings and other secondary sources
- The long-term goal of achieving full circularity
AMC at the Conference
Our team of mining specialists will be actively involved in presenting, exhibiting and engaging in conference activities.
Technical Session: Innovation and best practices in Mining: Operations and Processing
Topic: Dilution in mine planning
Author and Presenter: Wayne Rogers, Open Pit Manager / Principal Mining Engineer, AMC Consultants - Vancouver
Date: Monday 5 May
Time: 2:00 PM - 2:25 PM | 513C
Abstract:
Any financial evaluation of a project requires realistic assumptions of throughput rate and grade as well as mining rate of ore and waste. A realistically diluted resource model provides a basis for developing realistic production schedules and financial outcomes for a project.
There are many different methods of applying dilution and ore loss and the method chosen should be suitable to the deposit type, mining and processing methods, and the level of study. Deposit types vary in the distribution of mineralisation, thickness, dip, strike and continuity of mineralization.
Mining considerations include the selective mining unit (SMU), bench height, mining equipment size and configuration, and grade control strategy.
Processing considerations include the processing throughput rate, blending, ore sorting techniques and recovery.
This presentation discusses the most common methods used to apply dilution and ore loss, presents case studies, and introduces some of the new and emerging techniques.
Technical Session: Innovation and best practices in Mining: Operations and Processing
Topic: Ground support strategies for weak rock mass in underground mining and tunneling
Author and Presenter: Dr.
Ying Liu, Principal Geotechnical Engineer, AMC Consultants - Vancouver
Date: Tuesday, 6 May
Time: 10:55 AM - 11:20 AM | 515A
Abstract:
Mining and tunneling in weak and highly fractured rock, soft soils and mixed ground present challenges in maintaining a safe working environment, excavation stability and operational efficiency. Traditional ground support systems - such as reinforcement (grouted rebar, friction bolts and cable bolts) and surface support (mesh, shotcrete and shotcrete ribs /arches) - commonly used in mining industry often prove ineffective for very poor ground conditions.
This paper introduces an innovative ground support system which combines use of self drilling anchor and shotcrete to address these challenges. The support system provides both active and passive support functions. Self drilling anchor serves as rock reinforcement, consolidating rock mass and enhancing rock mass strength. Additionally, they can be used for spiling as pre-support, as well as for stabilizing faces for large-section excavations. Shotcrete, when applied in weak ground, has two functions: (a) to act as a structural arch support the ground pressure, and (b) to seal the exposed ground immediately
after excavation to prevent loose material form unraveling, reactive rock / soil materials from swelling, face instability and ground collapse.
This paper outlines essential design considerations, practical approaches for pre-reinforcement and support in weak rock, and implementation measures. Three case studies illustrate the application of these pre-reinforcing and support measures in underground mining and tunneling, demonstrating improved excavation stability and reduced cycle time to enhance productivity.
