Pit Slope Stability Calc

Designing a pit wall and need to check if it will hold? Enter slope geometry, material properties, and water table conditions to get Factor of Safety with pass/fail status — before you commit to a bench design. Supports planar slide, circular (Bishop), and wedge failure modes. Choose from 7 material presets (hard rock through mine waste) or enter custom cohesion, friction angle, and unit weight. Accounts for water table and seismic loading. WHAT IT CALCULATES: - Factor of Safety (FoS) with color-coded status - Driving force vs. resisting force breakdown - Stability rating: stable, marginal, unstable, or failure - Water pressure and seismic load effects - Critical failure surface parameters MATERIAL PRESETS: - Hard Rock (Granite) - Medium Rock (Sandstone) - Soft Rock (Shale) - Stiff Clay - Dense Sand - Compacted Fill - Mine Waste/Tailings Built for mining engineers, geotechnical engineers, and quarry operators.
