一、推行旁側給水降低粉尘的理論根据 (一)采用旁側給水时,空气不会进入炮眼而妨碍粉尘的湿潤。中心給水时压縮空气(自活塞水針孔周围隙縫喷出的)籍水由水針射入钎子孔时,在钎尾眼口处造成的負压,以及本身的冲力进入钎子中心孔,繼而进入炮眼。这就大大地妨碍了水对矿尘的湿潤能力,如图1。 First, the implementation of lateral water supply to reduce the theoretical basis of dust (a) the use of side feed water, the air does not enter the blasthole and hinder the wetting of dust. When the center water supply compressed air (from the piston water hole around the pinhole) water from the water into the hole when the hole, the end of the hole in the end of the cement caused by the negative pressure, and the impact of its own into the center of the hole , Then enter the hole. This greatly hinders water wetting ability of dust, as shown in Figure 1.
