The utility model discloses a tunnel excavation blasting after sprinkler dust, it is in the working face from shooting 10 meters to 20 meters from the sprinkler pipe on the installation of a ball valve and the frame, the installation of a rotating door frame, the door is in the closed rotational contact position when the ball valve and the handle. When blasting, the shock wave impact on the door plate rotation, so that the ball valve is opened, automatic sprinkling dust. Because the utility model is far away from the blasting point, so it is not easy to be damaged, as long as there is the will to open the valve, solves the defects of artificial opening.
