Abstract: Aiming at influencing factor problems about gas dynamic emission in heading face, the paper researches the relationship between gas dynamic emission and tunneling technology. It makes a matlab program, and builds a data processing model of gas dynamic emission by the statistic and analysis of gas concentration time series data in the return airway of Jizhong Energy Shares Company Dongpang Mine twelve mining area. The analysis results show that there are obvious differences in gas emission in different tunneling technologies, drilling operations and tunneling operations have a greater influence on working face gas concentration.
