Stability of the roof near karst disturbances at the Leningrad shale deposit based on density γ-γ- logging data

Abstract
Estimating the strength properties of a rock mass by extrapolating the physical and mechanical properties of rock samples is inefficient due to the influence of the scale factor. Both geological and mining features of the deposits influence rock stability. Methods are needed to study rock properties directly in the mass. In this respect, the γ‑γ method of measuring the density of rocks in natural occurrence has great possibilities, since the density of rocks in the mass is either functionally or correlatively related to other physical and mechanical properties of rocks.
