Geomechanics for safer, more productive mining operations
JM Geomechanics supports mining teams with practical geotechnical engineering, calibrated analysis and operational advice for underground and open pit environments.
Mining clients need geotechnical advice that is technically credible, practical on site and aligned to operational constraints. JM Geomechanics helps clients understand how ground conditions react to mining based on the extraction sequence and mining geometry. We take into account the impact of induced stresses, ground water conditions, geological structures to rock mass response during mining. These in turn affect and influence safety, productivity and efficiency.
Our work supports both the strategic and operational sides of mining: from geomechanical data collection, conceptual design to detailed mine design that incorporates advanced numerical modelling .We provide these inputs to mine planning and design as part of geotechnical risk hazard management during operations. We also help with operational site base geotechnical support.
Underground mining technical support
For underground operations, JM Geomechanics provide services in all underground mining methods starting from mining planning and design, mining geomechanics, numerical modeling, and operational site support. Key areas of support includes but is not limited to:
- Stope stability, pillar performance and brow/abutment assessment
- Ground support design and support performance evaluation
- Seismic response calibration and rock mass damage forecasting
- Extraction sequence, mine layout and block dimension optimisation
- Fall of ground investigation and practical ground control recommendations
Open pit mining support
For open pit operations, JM Geomechanics supports pit slope stability, geotechnical domain development, monitoring, hazard management and slope management planning. The work considers geological structure, rock mass quality, water, depressurisation, mining sequence and operational exposure.
- Pit design support from data collection to detailed design reporting
- Pit wall, waste dump and tailings-related slope monitoring support
- Slope Management Plans and Geotechnical Hazard Management Plans
- Dewatering and depressurisation monitoring considerations
- Risk management support for safe mining under geotechnical hazards
From observation to decision
The JM Geomechanics approach links site observations with analysis and implementation. Data is collected and checked, geotechnical domains are developed, modelling assumptions are calibrated where possible, and outputs are translated into recommendations that mine teams can use.
1
Understand
Review mine geometry, geology, stress conditions, geotechnical history, monitoring records and operational constraints.
2
Investigate
Collect and interpret the geotechnical data needed for rock mass characterisation, domain development and design inputs.
3
Analyse
Apply fit-for-purpose numerical modelling, empirical methods, mapping, monitoring and back analysis to assess ground behaviour.
4
Recommend
Provide clear design inputs, controls, monitoring requirements, ground support advice and reporting suitable for site implementation.
5
Calibrate
Compare predicted behaviour with observed performance, monitoring and damage mapping so models and controls improve over time.
