Analýza geologických podmínek horninového masivu spodních sušských vrstev v ochranném pilíři jam závodu sever Dolu ČSM

Abstract

Bachelor thesis is devided into two parts. The first one comprises bibliographic research and exloration of the geological, lithological and structural properties in the wide context of the studying region, which is shaft safety pillar of the ČSM-Nord Coal Mine in the Karviná Subbasin. Karviná subbasin is a part of the Upper Silesian Coal Basin (USCB). The USCB sedimented in Carboniferous and to the main deformations came in the Variscan Orogeny. In the second part is the lithology, and structure of rock mass in the above defined region analysed. The properties were analysed which can influenced the stress state and possible deformation in the rock mass. I tis very useful and significant for mining and mine working stability.
