Optimisation and Application Study of On-Board Spray-Guided Dust Reduction Device for Coal Mining Machine
Gaozhuang Coal Industry 3 under the 502 working face as the research object,the coal mining machine cut coal body section wind speed and dust distribution characteristics of the analysis,coal mining machine on-board spray ejection control and dust reduction device from the spray ejection air volume and structure of two aspects of the optimization of the design,the results of the application of practice show that:application of the optimization of the control of the reduction device,can be controlled on the dusty wind flow,the driver of the coal mining machine cutting the driver's respiratory and total dust of 92.7％dust reduction efficiency,respectively,of the dust reduction efficiency.The efficiency of dust reduction reaches 92.7％and 86.5％respectively,and the effect of dust control and reduction is remarkable.
