Job Description

Under the general supervision of the Senior Geotechnical Engineer, the Underground Geotechnical Engineer is responsible for reviewing mine plans and providing expertise by applying rock mechanics principles to underground mine designs. The role includes leading and assisting in various ground support designs, numerical modeling, and planning projects. Additionally, the engineer ensures adherence to the Ground Control Management Plan through quality assurance and quality control (QA/QC) strength testing, monitoring, and audits.

This is a unique opportunity for cross-training in open pit and dam geotechnical fields. The role involves providing geotechnical supports including field instrumentation, field mapping, geotechnical monitoring with slope stability radars and instruments, blast vibration monitoring and analysis, rockfall management, slope design reviews, and hydrogeology.

Operational Responsibilities

• Design and develop ground support standards for underground excavations to ensure stability and safety.
• Adhere to ground control QA/QC programs, including conducting bolt pull-testing and compressive strength testing of grout, shotcrete, and backfill materials.
• Support and maintain the Ground Control Management Plans, ensuring they are up-to-date and effective.
• Assist in the development and delivery of ground control safety training programs to educate mine personnel on best ground control safety practices.
• Perform regular geotechnical field inspections and audits of active mining areas to identify ground control hazards and implement mitigation actions.
• Develop rehabilitation plans for areas requiring ground support and track the progress of ground support actions.
• Review mine designs and plans to ensure they are consistent with rock mechanics principles and geotechnical standards.
• Conduct geotechnical mapping and core logging to document rock mass characteristics and inform ground or mine design.
• Create and support mitigation ground support plans to address identified geotechnical risks and enhance mine safety.
• Provide geotechnical support for open pit and dam construction activities, including field instrumentation, geotechnical mapping, geotechnical monitoring with slope stability radars and geotechnical instruments, blast vibration monitoring ana analysis, rockfall management, slope design reviews and hydrogeology, as needed.
• Ensure all geotechnical activities meet required standards and maintain a register of risks and opportunities.
• Support the effective execution of the Underground Business Plan by mitigating potential schedule risks.
