一、推行旁侧给水降低粉尘的理论根据(一)采用旁侧给水时,空气不会进入炮眼而妨碍粉尘的湿润。中心给水时压缩空气(自活塞水针孔周围隙缝喷出的)籍水由水针射入钎子孔时,在钎尾眼口处造成的负压,以及本身的冲力进入钎子中心孔,继而进入炮眼。这就大大地妨碍了水对矿尘的湿润能力,如图1。(二)旁侧给水能保证了先开水门后开风门,先闭风门后闭水门的措施,消灭了干式打眼现象。在中心给水时,为了避免水进入气缸,我们认为应将风水
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) Ji Shui injection by the water hole into the hole when the hole in the end of the drill hole caused by the negative pressure, as well as their own momentum into the center hole of the solder, Then into the hole. This greatly hinders water wetting ability of dust, as shown in Figure 1. (B) side of the water to ensure that the first open the door after the opening of the water door, closed the door after the closure of the first damper measures to eliminate the phenomenon of dry-type drilling. In the center of the water supply, in order to avoid water into the cylinder, we think Feng Shui should be
