THE MOHR-COULUMB FAILURE CRITERIA AND MOHR'S CIRCLE

Things to note before using this tool are: 

1. This tool aims to help determine the Mohr circle in relation to the failure envelope line and the value of the plane orientation in relation to the principal stress axis

2. Rock stability occurs when the Mohr circle does not touch the failure envelope line.

3. Rock conditions are fractured when approaching the failure envelope line.

4. Rock conditions are broken when crossing the failure
