摘要
介绍一种针对采煤机内外喷雾降尘效果不理想而设计的负压二次降尘技术 ,它实现与作业现场粉尘浓度相适宜的自动运行与停止 ,达到高效节能的目的。
In view of the unsatisfied results of dust control with outer and inner mist spray at the coal cutter, the technique of secondary dust control under negative pressure was designed. It has realized the automatic operation and stop proper to the worksite dust concentration and achieved the target of high efficiency and energysaving.
