Design and Comparative Application of Dust Reduction Devices in Coal Mining Face
In order to reduce the dust concentration around the coal mining machine and improve the effect of dust management in the comprehensive mining face,through the analysis of the dust reduction mechanism,optimize the design of a high-speed water jet negative pressure dust reduction and dust removal device,after the installation of the device on-site,in the coal mining machine mining,the whole dust around the coal mining machine,dust suction reduction rate of 60%to 80%,and the dust at the drum of the coal mining machine has a great inhibitory effect,and significantly reduces the drum in front of the Dust concentration,isolate the dust between the scraper conveyor and the coal miner rocker arm to spread to the pavement,reduce the dust concentration of the comprehensive mining surface.
