Abstract According to the current situation of gas control problems in No. 15 coal seam of Baoan Mine, the gas prevention and control technology of gas comprehensive control was discussed, and the scheme suitable for gas control of strips in the security coal industry was clearly identified. Through the successful application of this scheme, the purpose of safe excavation and mining in the mine under the unfavorable conditions of large gas emission, complex geological structure and prominent danger was realized, providing reference for mine safety production.
