Abstract. An analytical description of the coal seam stress state, including tectonic disturbance with closed beaches was represented. Disturbance area was presented as elliptical inclusion. Introduction of a complex variable in the equations system by substituting the values of the current coordinates x, y has to determine the stress field in the bottom hole of the coal seam in the zone of tectonic disturbance within the area, the size of which may substantially exceed the crushing area, feathering development gaps and physical-chemical conversion, taking into account role of fluids in the formation of deformations. Stress state is defined as a superposition of two solutions of the reference pressure of the coal seam and discontinuous dislocation zone. Changing the parameters of the elliptic inclusion and physical-mechanical properties of the coal seam help to evaluate state state of a broad class of discontinuous structures.

Keywords: tectonics, stress state, discontinuous structure, fluid.
