We completed large-scale work to update frame and block geomechanical models at the Gross Cluster (Gross and Tabornoe fields)
At the end of 2024, CMT Consulting completed large-scale work to update frame and block geomechanical models at the Gross Cluster (Gross and Tabornoe fields).
The Gross cluster is well known to our employees: we have visited this mine several times. Among the completed tasks were field mapping of quarry sides, participation in the drilling of geomechanical and hydrogeological wells, as well as zoning and stability calculations of design contours.
To carry out large-scale work to verify the existing lithological-structural frameworks, unmanned surveys were carried out of the entire area of the mined quarries. The total survey area in plan was 3.7 km 2the depth of each quarry reached about 220 meters. Several thousand detailed photographs of ledges and sides were taken at close range, which made it possible to study the identified structures in detail. It took an average of 4 days to survey one quarry.
Based on the results of the survey, it was possible to exclude previously assumed faults and identify new ones that were not previously taken into account, as well as collect extensive data on the layering of the massif.
The block geomechanical model has been substantially refined to reflect updated information from the 2022 field work.
We expect that the new models will demonstrate their effectiveness and will be regularly updated by the mine’s geomechanical service in the future.
