FF GeoMechanics delivers geotechnical and geomechanical studies for mining operations, projects, tunnels and civil works, both nationally and internationally. Studies comprise pre-feasibility, feasibility, and detailed engineering, geomechanical risk analysis, rockmass characterization and stability assessments.

We have a vast experience on submitting engineering studies that have been reviewed and accepted by the Chilean Mining Department (SERNAGEOMIN) and the Chilean Environmental Department (SEA) which demonstrates the accomplishment of current safety and environmental standards, and legal requirements.

Our underground engineering studies comprise:

1. Geotechnical and geomechanical studies and stability assessments for different underground mining methods including block and panel caving.

2. Mine design and stability assessments for: stopes, major excavations, underground chambers, shafts and pillars.

3. Back-analysis of failures and underground instabilities.

4. Design, analysis and assessment of ground support & reinforcement systems.

5. Analysis of underground and surface (open pit) interaction, including subsidence and caving.

6. Ground control management plans.

7. Design of geomechanical instrumentation and monitoring systems.

Our open pit engineering studies comprise:

1.  Geotechnical and geomechanical studies and stability assessments.

2. Slope engineering and stability assessments.

3. Back-analysis of failures and open pit instabilities.

4. Design, analysis and assessment of slope support & reinforcement systems.

5. Analysis of surface (open pit) and underground interaction, including subsidence and caving.

6. Ground control management plans.

7. Stability assessment and design of waste rock dumps, heap leaching piles and tailings dams.

8. Design of geomechanical instrumentation and monitoring systems for slopes.

FF GeoMechanics has developed a significant number of 3D finite element numerical models by using the RS3 software (www.rocscience.com). In addition the company owns the licence of 3D limit equilibrium software (SLIDE 3D) for the stability assessment of slopes, rock dumps, piles, etc.

FF GeoMechanics Consultants has specialized on using the Rocscience Suite and Leapfrog licence for the construction of geotechnical rock mass models.

FF GeoMechanics owns a rock mechanics testing facility fitted with last generation equipment imported from Europe.

Equipment and instrumentation are frequently calibrated by CESMEC (Bureau Veritas) Certification. In addition the laboratory professionals hold accreditations granted by the Chilean INN Standards Institute in accordance with NCh-ISO-IEC-17025:2005

Our team offers "on the field" innovative solutions, such as:

1.  Indirect determination of uniaxial compressive (unconfined) strength by the use of an esclerometer (Schmidt Hammer).

2. Assessment and monitoring of internal damage on pillars by using an endoscope (or bore-hole camera).

3. Deformation and displacement monitoring through a digital extensometric tape.

4. Design and implementation of rockmass damage assessments systems.

5. Development of ground control management plan (GCMP).

6. Geotechnical and geomechanical courses, training and mentoring, including ground support topics.

7. Geomechanical training courses, including fortification modules, monitoring and instrumentation and quality control of support systems.

8. Training, training and mentoring of geomechanical work team.
