在煤矿防尘工作中,运输大巷降尘也是一个重要环节。装载煤炭的矿车在运输过程中,会造成煤尘飞扬,它严重影响生产环境和工人身体健康。为了搞好矿井防尘工作,我们于1983年试制成功了接触式煤车自动洒水装置,使煤车满载煤炭后被自动喷雾洒水装置均匀洒湿。这样在运输过程中,就大大地减少了煤尘飞扬,使煤尘由原未采取喷雾措施的24.5mg/m~3下降到2.8mg/m~3取 Dust in the transport of dust in the mine work is also an important part. In the course of transportation, coal-loaded coal mines can cause the dust to fly, which seriously affects the production environment and the health of workers. In order to do a good job dust mine work, we successfully trial in 1983 trial contact coal car automatic sprinkler device, the car full of coal after the automatic spray sprinkler uniform wetting. In the process of transportation, the dust of coal dust is greatly reduced, and the coal dust is reduced from 24.5mg / m ~ 3 which was not sprayed to 2.8mg / m ~ 3
