## What is 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. Works offline.
