On tectonic disturbance of some mine fields of the
Abstract
Among the developed coal deposits of the USSR, the Suchan deposit is one of the most complicated by geological features and mining and operational factors. It is characterized by the following main features. The deposit is strongly dislocated. Pliquefactive and disjunctive tectonics is sharply expressed. Coal seams (as horizons) are pronounced but variable in thickness and quality. The coal-bearing strata along the weakening planes are cut by eruptive rocks with manifestations of contact metamorphism. Due to the fact that anticlinal parts of the folds are denuded to a large extent, the developed coal seams are contained in synclinal parts of the folds. It is of undoubted interest to find out from the exploitation data the distribution of displacements and the forms in which they appear in these conditions.
