Influence of heterogeneity of coal layer durability on change of press-deformed condition of the anisotropic coal massif occurring during conduction of mining works in zones of geological faults is considered. Research of influence of heterogeneity of a layer on the basis of the decision of a problem of the theory of elasticity is carried out. Estimation shows essential increase of gas-dynamical danger when conducting mountain works in zones syngenetic faults is shown.
