To protect the safety of personnel in buildings adjacent to gas extraction pump rooms, it is necessary to set up blast walls to separate areas with explosion hazards in the factory building. Due to the lack of relevant regulations in the coal industry, there is currently no content related to blast resistant design. This article refers to relevant anti explosion design specifications in the petrochemical industry, anti explosion chamber design specifications, and other literature and books to introduce the characteristics, modes of action, and calculation of explosion shock wave related parameters of indoor and outdoor explosion loads. It briefly explains the process and formula application methods of anti explosion structural design. On this basis, combined with the layout of the Wangfeng Mine Gas Extraction Station, an anti explosion wall design was carried out adjacent to the gas extraction pump room building, providing safety protection for its internal staff.
