Analysis on current situation of explosion door for vertical air shaft in coal mine

Explosion door of air shaft in coal mine is an important safety equipment to protect the main fans. In the major mine explosion accidents happened in this century, the problems of accident enlargement caused by design defect of explosion door for air shaft have occurred frequently, which has made the explosion door of air shaft in coal mine attaching attention of multiparty, and it has gained rapid innovation and development. The making of relative regulations and standards on explosion door of air shaft in coal mine at home and abroad was hackled. The structure, characteristics and explosion-proof principle of more than a dozen typical explosion doors were analyzed, and the relative research results of theories and experiments were introduced. On this basis, the existing problems in the development of explosion doors were highlighted, and the directions and thoughts to solve these problems were put forward.
