Abstract: When coal plants are closed or preserved, partial or complete inversion of the man-made regime of underground waters takes place, which can lead to catastrophic regional environmental consequences such as flooding of under-worked areas, activation of rock displacement processes, destruction of powerful rock layers. This paper proposes a generalized interpretation of the mechanism of the relationship between the strength characteristics of sandstone layers in the coal-plated C26, which is being worked out by the mines of Donetsk and Makeevka. The results of studies were presented, which allowed to detect the relationship between the parameters of the composition and the structure of the whistle, as well as the analysis of strength as a result of long-term moistening, which leads to brittle destruction, according to the effect of P. A. Rebinder.
Keywords: coal bed, whistle, sandstone, Rebinder effect, destruction, seismic phenomena.
