Review of the PMC Tailing Storage and Coffer Dam Facilities
Philsaga Mining Corporation
Agusan Del Sur
Philsaga Mining Corporation (PMC) engaged AMH for the conduct of studies related to its Tailings Storage and Coffer Dam Facilities in Rosario, Agusan del Sur. The earth-dam Tailings Storage Facilities serve as containment for tailings which are part of the by-products of processing gold ore. PMC directed the conduct of due diligence studies and review of existing designs as part of its risk management initiatives. The scope of AMH included geotechnical drilling and laboratory testing, slope (limit equilibrium and finite element) modeling, seismic risk assessment, hydrologic modeling and hydraulic assessment. For this project, AMH used specialized software tools including Slide 6.0® by Rocscience, Plaxis 2D® for finite element modeling and deformation analysis, HEC- HMS by the US Army Corp of Engineers, and Civil 3D® by Autodesk.
