Abstract
Distributions of methane gas concentration at a heading face with an auxiliary fan were measured in both an actual coal mine and a scale model. As a result, general distribution pattern of methane gas concentration was elucidated and it was found that there exist several areas where gas concentrations tend to rise to dangerous levels. A CFO (Computational Fluid Dynamics) method was also developed and the results of the computation were compared with those obtained in these measurements. It was concluded that the CFD can be used for simulating the distributions of gas concentration that are affected by conditions in a heading.
