This article is a basic study dealing with the issues of underground storage of carbon dioxide generated from different kinds of activities. Carbon dioxide can be stored underground as a free gas; gas dissolved in water, or can be adsorbed in the rock mass and in the remaining seams. The technology for processing and storage of carbon dioxide is known as Carbon Capture & Storage (CCS). The article focuses on the possibility to store CO2 underground at the Paskov Mine in the Czech Republic. Tento článek je základní studií zabývající se problematikou ukládání oxidu uhličitého, vznikajícího z různých druhů činností, do podzemí. Oxid uhličitý je možno ukládat do podzemí jako volný plyn, plyn rozpuštěný ve vodě nebo může být adsorbován v horninovém masívu a ve zbylých slojích. Technologie zpracování a ukládání oxidu uhličitého je označována jako Carbon Capture & Storage (CCS). Článek se zaměřuje na možnost ukládání CO2 do podzemí v Dole Paskov v České republice.

The question of mining under the main haulage level as a way by which in some cases coal reserves can be effectively extracted is still discussed. The paper introduces advantages and disadvantages of this method. It presents examples of the bedding of a seam in a limited depth under level, for example 50 m, when the opening by the under level mining method is obviously more advantageous. Special attention is given to risks of ventilation short circuit which are higher in this method compared to classical opening. The paper also gives a brief economical reflection allowing to determine the efficiency of under level mining.
