STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES
what is the rock mass strength. Knowledge of roc k mass strength is also important in the design of support systems as discussed in the next set of notes with regard to the concept of rock-support interaction. In general, rock mass strength depends on the strength of intact rock and the strength of rock discontinuities.
