## Description

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.

Calculate rock pillar stability using the Obert-Duvall empirical formula

## Prompt Examples

**Prompt:** 
```
Calculate the stability of a pillar with a width of 5m, height of 10m, UCS of 50MPa, and vertical stress of 15MPa.
```

**Response:** 
```
The calculated pillar strength is 32.5 MPa, resulting in a factor of safety of 2.17, which indicates a stable pillar.
```

**Prompt:** 
```
What is the stability for a 3m wide, 12m high pillar with 40MPa UCS and 20MPa stress?
```

**Response:** 
```
The pillar strength is 18.4 MPa, yielding a factor of safety of 0.92. This pillar is considered unstable.
```

**Prompt:** 
```
Check stability for a pillar: width=8, height=4, ucs=60, verticalStress=25.
```

**Response:** 
```
The pillar strength is 84.0 MPa, providing a factor of safety of 3.36, confirming high stability.
```

## Frequently Asked Questions

**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.
