Description	Monitoring of the concentration of methane (CH4) in the air of mines is one of the most important security criteria. Methane is flammable and mixed with air it is explosive in the range of 5-15 %. With the constant release of methane in mines is necessary to reduce the concentration of methane ventilation or degassing. Even though the great progress was done in the prevention of potential threats to human lives and property by the occurrence of methane, it is important to explore new technologies that can lead to improved understanding and prevention of hazardous situations and thus anticipate risk situations. One of the tools that can be used to prevent dangerous situations influenced by occurrence of methane is the technology of numerical modeling of flow, globally known as CFD (Computational Fluid Dynamics) programs. Using modeling in CFD program and follow-up simulations we can verify the variations of specific interventions and then find effective alternatives. The purpose of this paper is the using this technology, numerical modeling of flow using by CFD software Fluent from Ansys, Inc., for simulation and modeling of mine gases flow, respectively methane, from underground toward to the surface and especially around the borehole.
