Research on Comprehensive Dust Control Technology and Its Application Effect
In order to reduce the dust concentration of the working face and achieve effective dust control,the comprehensive dust control technology of segmented water injection+high-pressure spray is designed.The application of segmented water injection technology not only reduces the original dust concentration,but also effectively solves the problem of poor hydrophilicity by adding wet dust suppressants to water.It is verified that when only spray dust reduction technology is used in the working face,the dust reduction efficiency of the total dust concentration at 15 m from the return air side is 72.9%.After the comprehensive dust reduction technology is used,the dust reduction efficiency at the same location is as high as 90.8%,which indicates that the comprehensive dust reduction technology has significant effect.
