Summary

Research interests

• Stability w88 for open pit mines including overall pit slope w88 and maintenance, w88 of slope angles and catch benches, structural geology modeling, estimating rock mass properties, numerical modeling for slope stability assessment, back-analyzing slope failures, specifying remedial measures (dewatering, buttresses, step-outs, etc.), and slope quality assurance/control (QA/QC).
• Stability design for underground mines including open-stope, cut-and-fill, room-and-pillar, longwall, and block caving methods, providing guidelines for safe underground w88 design (i.e., panel spans, extraction ratios, pillar widths), designing support systems, backfill w88, seismic risk assessment, prediction of caveability, fragmentation, recovery, infrastructure stability, and surface subsidence.
• Fractured modeling using Discrete Fracture Network (DFN) methods for rock mass characterization and modelling of block and panel cave projects for fragmentation prediction.
• Blast w88 and assessment for surface and underground mines.
• Mine safety and health audits identifying potential hazardous conditions and evaluating w88 practices for compliance with safety and health laws and regulations.
• 3D structural and geological model construction for geotechnical data interpretation.
