A geotechnical engineer in mining ensures the ground stays where it should. Their job is to understand how rock and soil behave when excavated, drilled, or loaded. They also design systems that keep people, equipment, and infrastructure safe.
If you’re interested in the field, here’s what that looks like on site:
A mix of fieldwork and analysis
Geotechnical engineers split their time between being on site and in the office.
On site, they inspect pit walls, monitor slope stability, collect ground movement data, and check instrumentation like prisms and piezometers. In the office, they analyse results, model slope performance, and report on ground risk.
No two days are identical. Heavy rain, blasting schedules, or unexpected wall movement can quickly change priorities.
Daily responsibilities
A geotechnical engineer will often:
- Conduct site inspections and stability assessments.
- Review blast designs and monitor pit wall performance.
- Manage geotechnical monitoring systems and data.
- Support mine planners and drill-and-blast engineers with slope angles and berm designs.
- Prepare geotechnical reports and risk assessments.
In underground mines, this focus shifts to rock support systems, ground control monitoring, and seismic risk management.

Working environment
Most roles are FIFO (Fly-In Fly-Out) or residential at operating mine sites. Rosters are often 8:6 or 2:1, with 12-hour shifts. In this career, you’ll need to be comfortable in remote conditions. You’ll also need to walk active pits or underground drives, and work closely with production crews.
Safety is a constant focus in this environment too. Every inspection starts with a risk assessment, and situational awareness is vital when operating near heavy equipment or high walls.
Tools and technology
Geotechnical engineers rely on:
- Slope monitoring radar and prisms for ground movement detection.
- Drones and photogrammetry for pit mapping.
- Software tools such as Slide2, Rocscience, or Deswik for modelling and design.
- Data management platforms that integrate with mine planning systems.
Strong digital skills are essential. You’ll often use real-time data to make quick, high-stakes decisions.
Your team
Geotechnical engineers work within technical services teams. They often collaborate with:
- Mining engineers for slope and haul road design.
- Geologists for rock mass characterisation.
- Production teams to implement safety controls.
You can expect to brief superintendents and managers on any geotechnical issues that could impact production too. In this role, your communication skills are just as important as your analysis.
If you’re analytical, practical, or enjoy problem-solving outdoors, a geotechnical career in mining may be right for you. Though conditions can be tough and unpredictable, the work directly affects safety and operational continuity. It offers strong progression, diverse work, and the satisfaction of keeping the operation strong.
