A series of tests was conducted to investigate the blast resistances of the building to premixed methane-air interior burning and explosion. Explosion prosecess of the gas methane medium (in the inner space) extremly depend on the object site configuration. An interior deflagration of premixed methane-air burning and explosion in a specific vented chamber can happens due the all hazards: natural, criminal, terrorist, and accidental. The full scale object was tested as control specimen. LVDTs and pressure transducers were used to record deflection histories, and pressure sensors measured airblast pressure histories. In the first stage of a study two experiments of methane-air system in differ proportion were carried out.
