Abstract
Estimating the strength properties of a rock mass by radiating the physical and mechanical properties of rock samples is inefficient due to the influence of scale factor. Both geologic and mining engineering features of the deposits influence rock stability. It is necessary to study rock properties directly in the massif. In this respect, the U-method of measuring the density of rocks in natural occurrence has great possibilities, since the density of rocks in the massif is either functionally or correlatively related to other physical and mechanical properties of rocks.
