This work was developed from a theoretical and experimental study on the stability analysis of underground workings located in strongly metamorphosed andesite and determination of mine pressure in the context of rock – support system interaction. We thank to our colleague dr. Gabriel Băbuţ for his assistance and support in developing the mathematical model based on the principle of proper conformity and safety level, according to the main factors that influence the stability of underground workings. We would also like to show our gratitude to the University of Petrosani which provided the necessary equipment to perform all laboratory tests in prior experimental researches leading to the results synthesized in this article.
