Embodiment Construction

[0010] Such as figure 1 As shown, a fine water spray subsection control belt lane dust process, a spray device 11 is arranged every 40-60 meters in the lane 10, such as figure 2 As shown, the spray device 11 includes a water inlet pipe 9, a water purifier 1, and fine water atomization nozzles 8 and 7 connected in series. The distance between the fine water atomization nozzles is 0.3-0.5 meters, and the water quality filtration accuracy reaches 1000 mesh. , water pressure 1MPa~10MPa 。

[0011] The specific structure of the spray device is that the water inlet pipe 9 connected in sequence, the water quality purifier 1, the ball valve 2, the nozzle pipe 4, and the nozzle pipe 4 are connected with straight-through nozzle seats 3, 5, terminal nozzle seats 6, and fine nozzles installed on the nozzle seats. Water atomization nozzle 8,7. Open the ball valve of the water supply pipeline to let the sundries in the pipeline flow away, then close the ball valve of the water supply pip...

Abstract

The invention belongs to the field of coal mine dust control and in particular relates to a process for controlling dust in a belt roadway by sections through water spray. The invention aims to solve the technical problem of control of coal dust in tape haulage roadways or intake and return air roadways. The process is characterized in that a spraying device is arranged every 40-60 meters in the roadway; water atomization spray nozzles are arranged on the spraying devices; the distance between the water atomization spray nozzles is 0.3-0.5 meter; the water filtration precision reaches 1000 meshes; and the water pressure is 1-10MPa. The process has the following beneficial effects: the aims of effectively controlling the dust concentration under the shaft and improving the labor hygiene conditions of the working surfaces are achieved; the dust in the roadway is reduced below the harm level; the safety of mine production is improved; and the health of miners and the working environment are protected.

Description

technical field [0001] The invention belongs to the field of coal mine dust control, and in particular relates to a process for fine water spraying to control belt lane dust in sections. Background technique [0002] The concentration of coal dust in the coal mine belt conveyor roadway or the shaft return airway generally exceeds the standard seriously, and the air flow velocity is 2-3 m / s. Generally, the underground static pressure water is used to spray dust directly. However, due to the unreasonable use and placement of the spray device, the formation of The quality of atomized water mist is poor, and the water curtain formed in many cases has large particles and uneven distribution, which is easy to wet objects and form water accumulation, so that part of the dust cannot be contaminated with water, and a good dust reduction effect cannot be achieved. Suspended dust not only pollutes the working environment, but also easily causes harm to workers' bodies, and is likely to...
