Research On Application Of Efficient Spraying Dust-settling Technology In The Digging Working Face

The digging working face dust-settling plays a very important role in mine dust control field. With advance of mine green safe manufacture, ho\v to improve the digging working face dust-settling efficiency has attracted great attention.Based on deep analysis of spray dust-settling mechanism, the paper has put forward main malpractices of conventional dust control methods. With the research actuality and orientation analysis of the dust control field, the paper has brought forward efficient spray dust control, a new dust control thoughtfulness.The paper has achieved efficient spray dust-settling design rules by analyzing facts affecting spray and dust control effect and accordingly designed efficient spray dust-settling system-heading spray sub-system and mist pole dust drop sub-system.Simulated test in lab and industrial test in mine have proved its spray and dust-settling effect.Theoretical analysis and experimental research have argued the efficient spraying dust-settling system of rational structure and notable dust-settling effect and it is worth popularization.
