Abstract

Based on the use of the special limit state condition, studies were conducted on the effect of moisture on the stratification of layered interbedded rocks for the case of overworked and then underworked interbedded rocks. The researchers paid insufficient attention to the effect of humidity on the stratification of interbedded rocks. As is known, the stratification of stratified rocks of the roof of mine workings significantly reduces their bending stiffness, which eventually leads to a significant increase in normal to the layering displacements of interlayered layers and the formation of limit zones. In this regard, prediction of the stratification of interbedded rock, with account of moisture, is important, as it is used in selecting the optimal parameters of the passports of mine workings, providing the necessary operational mode of mine workings, as well as in solving other important geomechanical problems.
