Abstract

Gas drainage as the means of securing of safety measures during mining operation in gassy mines of the Ostrava – Karvina Coal Basin

The bachelor´s work deals with the description of the drainage in a relationship to the Czech part of Hornoslezsky coal basin focused on the gas drainage which is in progress in the productive mines of Ostrava- Karvina coal basin. The introduction of the work contains the geological structure of Czech part of Hornoslezsky coal basin, its stratigraphy, lithologic development and tectonic structure with the possibility of natural gaseous hydrocarbons accumulation. Then I deal with the forms of gas drainage, the description of individual gas drainage systems, the infuence of the mine drainage on the safety operations of mines and legislative regulations governing the activity of mine gas drainage. In the bachelor´s work I also mention some findings from mining the firedamps in special allotments which started to be limited at the beginnig of the mining inhibition in Ostrava-Karvina coal basin. The conclusion is devoted to the contemporary possibilities of the economic drainage gaseous mixture utilization as the important energetical resources in our region.
