dc.description.abstract | The trouble geodynamic situation in a number of mines of the North Uralian Bauxite Basin that manifests itself in frequent rock bumps in the zones of tectonic disturbances necessitated structural tectonophysic investigations in a number of excavations and natural exposures. Various deformations of the massif enabled one to reconstruct the parameters of tectonic stresses that had occurred. The method of kinematic analysis of fractured tensile structure elaborated by O.I. Gushchenko and refined by V.A. Korchemagin was used for that. As basic parameters of tectonic movements the method has the pointing vectors of shifts and the spatialisation of shear fractures. It makes it possible to make use of the entire of faults and relaxed surfaces caused by displacements to reconstruct the parameters of stressed fields. As a result, compression stresses have been found to take place in the massif, whose magnitude considerably exceeds a theoretical value calculated for the corresponding depth without regard for tectonic forces. The orientation of maximal compression stresses is sublatitudinal that is perpendicular to the strike of the Ural structures. The minimal compression has been registered along the strike of the structures. | |
