Scoring Method
The workflow follows the Nicholas (1981) numerical selection method and the UBC adaptation. Each input contributes a score from -49 (eliminated) to 6 (strong fit), then the methods are ranked by total suitability score.
Mining Engineering Tools
Select a UBC mining method workflow or run preliminary pillar strength calculations for room-and-pillar layouts.
UBC Mining Method Selector
Use the existing UBC-based mining method selection workflow.
Pillar Strength Calculations
Estimate pillar stress, extraction ratio, pillar strength, and factor of safety using classic empirical equations.
Important Disclaimer
This tool provides preliminary guidance only. Engineering judgment is required, and results should be validated through detailed feasibility studies. This is not a substitute for professional engineering analysis.

Use With Care
Treat the output as an early ranking, not a final design decision. Site-specific geotechnical data, economics, environmental constraints, access, ventilation, sequencing, and operational risks still need detailed engineering review.
