how to explain stress in rock

[roache]

Looking for information sources that explain stress in rock. Have the task of educating non-technical underground staff on different aspects of stress to increase knowledge and therefore safety. Aspects to cover include are "what is stress", "stress around underground openings" and "stress in pillars" etc.

Thanks for any help
