The paper presents the potential areas in Bosnia and Herzegovina (BiH) for injecting CO 2 into underground geological formations by boreholes. Areas are determined based on the geological structure of Bosnia ana Herzegovina, and development of Miocene formations which are the most prevalent in the northern and northeastern parts of the country, in the central part of country and southwest of Bosnia and Herzegovina. Furthermore paper gives an overview of potentials for injecting CO 2 into abandoned coal mines, and abandoned salt mine.

Safety risk management in Bosnian-Herzegovinian underground coal mines is not based on a systematic approach and standardized risk management methods. Mostly there is a traditional approach present, i.e. reaction to incidents/accidents that happen. This paper aims to point out the need for proactive approach introduction with an emphasis on importance of ventilation systems failure mechanism simulation analysis in planning of people and property defense and rescue in crisis situations. Based on ventilation parameters measuring results for a given research site (brown coal mine), a model was developed on which a simulation analysis was performed for three characteristic ventilation failure cases: spontaneous oxidation at the longwall exit, collapse at the entrance to the longwall and methane outburst - preparation of a new excavation field. VnetPC and CFD “Fluent” software packages were used to simulate mine ventilation. Keywords: risk management, brown coal mine, safety, ventilation system, longwall, simulation analysis, VnetPC, Fluent.
