Experiments conducted with metallic water troughs in the coal dust explosion suface steel gallery reveal that water troughs are quite effective in arresting the spread of flame beyond the zone of the barrier. It is also found that when the troughs are free to be dislodged from the position of rest, flame extinction is more effective than the situation when the water troughs are fixed to the body of the gallery. The flame is found to move with an accelerated velocity and the distance of the quenching zone from the position of the barrier is dependent on the concentration of water present. There is an optimum concentration of water to be present in the barrier for preventing the propagation of explosion.
