Specialist training courses

Our team have created specialised courses focused on geotechnical data collection and rock mass modelling for efficient workings on mine sites.

Mine planning and design

Computerised mine planning & design for underground & open pits for pit optimisation. We also aid in the design of mining layouts, schedules & equipment selection.

On-site geotechnical advice

We can provide advice for both open pit and underground operations including pit slope stability and slope angles, underground stability and support design.

Project Audits & Reviews

Our team can carry out ore reserve audits and reviews. Undertake financial assessments, risk analysis, due diligence and competent persons reports. As well as strategic and technical mine planning reviews for companies and operating mines.

Mining Feasibility Studies

Our team can help with project management for multidisciplinary mining feasibility studies. As well as providing bankable feasibility studies.

The services provided by Dempers & Seymour are related to geotechnical mine design and mining engineering. We have developed a unique methodology for the 3-D representation of the geotechnical environment that has been used for mining projects.
