In 2014, there was an accident in an underground coal mine in Manisa Soma. In this accident, 301 employees died. It has been studied on this subject for about 3 years. The most important of these researches are; the tests carried out in the research gallery, comparison of the test results with the documents obtained from the mine officially after the accident and CFD analysis. The authors believe that the cause of death is a very large amount of toxic gas, which occurs after belt conveyor fire. In this research, the events which developed after belt fire experiments in a research gallery that has 16 m2 cross-section (same size with mine galleries) and 30 m length were investigated. The results of this research were used in CFD analysis to investigate the characteristics of belt fire in a mine. The data obtained as a result of CFD analysis were compared with gas sensors datas. The sensors located in mine before acident in the simulated mine. When CFD analysis results and sensor measurement results were compared, very important findings were obtained. These findings make prominent contributions to the Emergency Action Plan studies in underground coal mines and CFD analysis is crucial for determining the post-accident emergency strategy.
