克里沃洛格矿区各矿使用中的Э—230环隙式压气引射器,共有700多台,用于沿通风管道将新鲜空气输送到巷道。在内部装药爆破时,用此种引射器可使回采工作面短时间地增加空气流速。在后一种情况下它可用作喷雾器,从而提高通风强度,湿润工作
There are over 700 units of Э-230 annular gas pressure injectors used in the mines of the Krivolon Mining Area to transport fresh air along the ventilation ducts to the roadway. In the internal charge blasting, with this kind of ejector can make the mining face a short time to increase the air velocity. In the latter case it can be used as a nebulizer, thus improving the ventilation strength and wet working
