3. operation method
(1) Sprinkle water along the sidewalk side of the roadway, and add a valve at the water outlet end of the sprinkler.The door (or nozzle) is used to control the amount of sprinkling water and improve the dust-proof effect.
(2) The water pressure and water volume of the sprinkling site must meet the requirements of relevant regulations to improve the dustproof effect.
(3) When the water pipe joint is high, the sprinkler should stand on the high stool or wooden ladder to work, and have personnel to superviseProtection; water pipe joints and valves shall be matched, and the joints shall be tight and leak-proof.
(4) in the transport roadway sprinkling water lane, to set up a post around, observe pedestrians and vehicles;Stop sprinkling water when the vehicle passes.

(7) After sprinkling water to wash the lane, close the valve and coil the water pipe.
4. considerations
(1) Regular scouring of roadway dust accumulation, main inlet and return air lanes at least once a month to flush dust accumulation, mining area laneThe cycle of channel flushing and dust accumulation shall be determined by the mine chief engineer.
