Water Jet Vacuum Dust Suppression Device Used to Tunnel Development

Abstract:

At present domestic tunnel construction, dust is one of the main factors which impact the production efficiency, safety clean production. It not only pollutes the environment, but also threats the health of workers. This article start from the tunnel dust prevention, control measures, heading face negative pressure control dust, and spray jet with the dust, to do research about the mineral water jet dust negative pressure technology. Combining experiments and field test methods, Study the dust fall mechanism of the tunnel water jet vacuum dust suppression, the device parameters and the effect of dust, the application of the technology has great significance to reduce the dust concentration of tunneling face and improve the working environment of workers.
