Description

Technical Field

[0001] The utility model relates to the technical field of coal mine dust reduction, in particular to a coal mining dust reduction device. Background Art

[0002] Dust is a common pollution in the coal mining process. Firstly, it affects the health of workers. Secondly, excessive dust concentration will bring hidden dangers of dust explosion and cause safety accidents in coal mines. Therefore, this application proposes a coal mining dust reduction device.

The spraying range of the temporary spraying device in the prior art is only the area around the water pipe. The dust reduction range is relatively single and the practicality is poor. In addition, when the water mist is sprayed, a part of the water will gather at the back of the water spray pipe nozzle and flow to the equipment surface or the ground under gravity, which will undoubtedly cause a waste of water resources.
