What formulas are used for calculations?

The tool currently utilizes the Obert-Duvall empirical formula to determine pillar strength and stability.

What inputs are required for the stability tool?

You need to provide the pillar width, height, the Unconfined Compressive Strength (UCS) of the rock, and the applied vertical stress.

How is the factor of safety interpreted?

A factor of safety greater than one indicates the pillar is theoretically stable under the provided loading conditions.

This MCP server provides specialized geotechnical tools to design stable rock pillars. By using the pillar_stability_design tool, engineers can calculate pillar strength, factor of safety, and stability status using the Obert-Duvall empirical formula. It accounts for pillar geometry, rock strength (UCS), and applied vertical stress to ensure underground stability.
