DZIURZYńSKI, W.; KRAWCZYK, J.  e  PAłKA, T.. Computer simulation of air and methane flow following an outburst in transport gallery D-6, bed 409/4. J. S. Afr. Inst. Min. Metall. [online]. 2008, vol.108, n.3, pp.139-145. ISSN 2411-9717.

This article outlines the results of a computer simulation reproducing the transport of a mixture of air and methane following the outburst on 25 November, 2005 in transport gallery D-6, bed 409/4, at the 'Zofiówka' hard coal mine. Based on a mathematical model, numerical method and boundary conditions from the disturbance caused by the outburst, the Ventgraph system of computer simulation programs was adopted for the study. We performed a computer simulation of the influence exerted by the outburst on the propagation of the air and methane mixture, and compared the results of this simulation with those of the actual event as registered by sensors of the mine monitoring system. A validation of the model allowed us to present temporal changes in the concentration of methane and air along flow routes.

Palavras-chave : mine ventilation; outburst of methane; numerical simulation; monitoring system.
