摘要: Abstract This study addresses methane dispersion in a mine tunnel with discrete sources and various methods to handle it. Air flow behavior the are simulated utilizing computational fluid dynamics (CFD) approach. Various possible conditions which may occur investigated. Simulation results indicate that inside is influenced significantly by number as well location of quantity released from each source. Furthermore, application an innovative divider comprises volumetric control director, It found properly directing ventilation where accumulating can reduce concentration below safe level. In addition, it noted focusing at point more effective compared dispersing several points. provides some new ideas for designing “intelligent” underground system cost-effectively maintain critical value.
