Abstract: According to shortages of the mine passive flameproof installation in the prevention and control of the mine gas/coal dust explosion accidents occurred, a mine active explosion suppression system was researched and developed.The HS mine active explosion system with an intelligent and accurate distinguishment of si gnal, millisecond ultra high speed triggering and priming, timely monitoring and control type full automatic explosion suppression, programmed working status self detec tion and other technical features, could realize an active explosion suppression.The technology could be relatively complemented with the traditional gas/coal dust expl osion accident prevention technology, could upgrad from the passive prevention to the active prevention and could realize an effective disaster control.A safety protecti on could be established at the front line of the production.At the present stage, the HS mine active explosion suppression system would be mainly applied to the explosi on suppression safety protection with close distance to the mine high danger location.
