Investigation Supervision and Pre-Feasibility Study for the Implementation of Vacuum Consolidation at Martabe Tailings Storage Facility

The Investigation Supervision and Pre-Feasibility Study for the Implementation of Vacuum Consolidation at the Martabe Tailings Storage Facility were conducted to evaluate the feasibility of applying the vacuum consolidation method to soft soil conditions and long-term tailings embankment stability requirements. The scope of work included supervision of field investigations, evaluation of geotechnical soil characteristics, consolidation and deformation analysis, and preparation of a pre-feasibility study and recommendations for vacuum consolidation as a ground improvement method. Key challenges included potential consolidation settlement, soft soil deformation, long-term tailings embankment stability, and the need to accelerate the consolidation process within the storage facility area. The technical approach involved evaluating the performance of vacuum consolidation, optimizing ground improvement parameters and geotechnical monitoring, and developing soil improvement recommendations to enhance the stability and effectiveness of tailings storage facility management.
