In view of the favorable business environment owing to the tin price advance in the world, RUSOLOVO is setting about rehabilitation of one of the largest Soviet plants in nonferrous metallurgy—Solnechny GOK engaged in the mining and processing activities in the Komsomolsky ore province. Continuation of mineral extraction meant deeper level mining. Complicated geological and geomechanical conditions of mining required undertaking of integrated research including geodynamic zoning which involved studies into the actual terrain features and comparison of the results with the geological survey data. To that end, the digital terrain models based on the 30-m SRTM elevation data were used. With the help of free GIS Microdem and QGIS softwares, the models were visualized as elevation maps in light and shadow, color or shades of grey, as well as in the form of stereoscopic anaglyph maps. The analysis of this information helped i dentify separate rock masses enclosing mineral deposits and tectonic blocks inside them. The extremely complex tectonic structure of the Komsomolsky ore province, and the numerous recently active faults governed, first, the alternating horizontal stresses in rock masses and, second, the diversity of geodynamic regimes even in close-spaced areas. This is valid, for instance, for rock masses hosting the Pereval and Festival deposits occurring under equal structural control.
