Abstract.

On the basis of experimental data has been analyzed the structural state of the coal seam enclosing rocks in zones of tectonic disturbances. Using the method of X-ray analysis, based on the phenomenon of X-ray diffraction of crystalline substance, marked the common structural features that reflect varying degrees of stress state carbonaceous clay rocks. Established the presence of shear deformations in the structure of the studied species, caused by shear stresses, which makes it possible to predict not only explosive, but also in situ disturbances, which include bulges and small kinks coal seam. Completed quantitative and qualitative evaluation of defects in the structure of rocks will significantly improve not only the accuracy of the prediction of tectonic disturbances, but also the safety of mining operations in their areas of influence.

Keywords:
