In terms of Samsonov-Zapad Mine (Krasnodon Coal Field, Northern Donbass), the author presents the theoretical basis and calculation of distribution of smaller amplitude geological dislocations in a coal bed in the area of large overthrusts, which allows predicting the intersections of the dislocations and roadways at early pre-operation stages to a high degree reliability. It is shown that the wavelike behavior of stresses in a coal bed has a number of components: trend, trend-and-cyclic and cyclic, and a tectonic dislocation shows itself along conditional lines that retrace configuration of large overthrusts. The constructed model allows calculation of distances between large faults and localities geological dislocations in a coal bed within a mine field, these localities of geological dislocations are the most probable places of fracturing in the coal bed. The universal nature of prediction of tectonic damage in coal beds based on the presented model consists in the applicability of any prediction techniques to checking the calculated places of tectonic dislocations. Prediction of smaller amplitude fractures in flat lying and gently dipping coal beds within a mine field bounded by a medium- or large-amplitude fault uses the developed mathematical model and a sevenstep procedure. For the check recalculation, it is proved to be applicable to use log data from exploratory wells drilled within the limits of a mine area in interest. The described analytical approach to the exploratory well logs makes it possible to identify only such well log intervals that might be of interest for the prediction of places of the tectonic dislocations in a coal beds. This option allows mine specialists to save time and not to study long intervals which are of no concern for the geological dislocation prediction. The procedure has been trialed in mines of Sukhodol-Vostok, Molodogvardeiskaya and Samsonov-Zapad in the Krasnodon Coal-Bearing Field. The results obtained with the procedure for the tectonic dislocation prediction in coal bed k2n during preparation of inclined Zapad longwall 2 for the production in Samsonov-Zapad Mine are reported for the first time.
