Abstract

The invention discloses an underground fog gun dust settling method and device. The dust settling method comprises steps as follows: 1), a fog gun dust settling device is mounted and fixed at the topof a mine, an atomizing system and a multilayer annular spray ring are arranged in the fog gun dust settling device, the fog gun dust settling device atomizes a normal-state solution into water mist particles with size of 10-150 micrometers, the water mist particles are diffused in a large area after being accelerated by a pneumatic high-speed fan, and a large number of tiny water mist particles are gathered and float in air to form white cloud and fog; and 2), by controlling for the atomizing system, an air duct of a fog gun is controlled to rotate left and right and move in a pitching mannerto spray mist to the mine in a large range. According to the underground fog gun dust settling method and device, the dust settling effect is better; and the fog gun is hoisted at the top of an underground roadway, and normal transporation and construction of the roadway are not affected.

Description

Technical field: [0001] The present invention relates to the technical field of dust suppression devices, in particular to a dust suppression method and a dust suppression device for an underground fog cannon. Background technique: [0002] At present, my country's coal mining is dominated by underground mining, and the coal output of underground mining accounts for more than 93%. Due to the narrow space for underground coal mining, the working location is changeable, and the ventilation effect is poor. Therefore, during underground coal mining, tunneling, reloading, and transportation, a large amount of dust is generated, which seriously pollutes the underground environment. Dust produced in mining operations is extremely harmful. Its existence seriously threatens the safe production of coal mines, and more importantly, it endangers the health of workers and causes various occupational diseases. [0003] In order to reduce the dust in the coal mining process, it is necess...
