Abstract

The invention relates to a method for treating dust on a coal mine heading face by using aerial fog turbulent flow fluid. The method is used for removing dust on an underground coal mine fully-mechanized heading face and is characterized in that low-pressure compressed air is used as a main power source, normal-pressure water is used for wetting and modifying gas, and gas-liquid two-phase fluid ismixed, atomized and sprayed on the coal mine driving face. Through continuous turbulence vortex splitting and energy transmission, the driving face is covered, a dust fog removing area is formed on the coal wall of the driving face and repeatedly collides with dust generated in the production process of the driving face for multiple times, and fine dust particles are aggregated and coagulated infog drops and settle on the ground surface, so that dust dissipation and reentrainment do not occur in the space of the underground coal mine driving face. According to the method, underground coal dust explosion caused by dust flying on the driving face and malignant events caused by silicosis of workers are avoided, and application prospects and significance are very important. A device adoptedby the method is simple, reliable, easy to install, efficient in dust suppression and free of reentrainment.

Description

technical field [0001] The invention discloses a method for treating flour dust in coal mine excavation work by gas mist turbulent fluid, which belongs to the field of dust removal in fully mechanized excavation working faces in mines, and in particular relates to a method for controlling coal mine excavation flour dust by gas mist turbulent fluid fluid, which belongs to roadway ventilation and safety technology field. Background technique [0002] With the high-intensity mining of coal resources and the improvement of mechanization of fully mechanized roadways, the dust concentration in the air of the tunneling roadway has seriously exceeded the standard. The high concentration of dust seriously affects the working environment of the tunneling roadway, increases the wear and tear of mechanical equipment and endangers the health of workers. However, the amount of dust produced by the roadheader at the excavation face is the largest when cutting coal. For this reason, engine...
