喷雾降尘技术由于具有简单易行、经济而降尘效果较好的突出优点,一直为世界各产煤国家普遍采用。现已成为实现矿井综合防尘的重要技术措施之一。 在井下采、掘、装,运等主要生产环节中,由于作业环境的差异,喷雾降尘技术也相应具有各自不同的特点,除采掘工作面随机(采煤机、掘进机)喷雾外,通常把其他装运、转载及净化风流等场合所要采取的喷雾洒水措施统称作“定点喷雾”。本文仅就定点喷雾的一些技术问题进行讨论。
Due to its outstanding advantages of simple, economical and effective dust reduction, spray dust suppression technology has been widely adopted by various coal-producing countries in the world. Has now become one of the important technical measures to achieve comprehensive mine dust prevention. In the main production steps of mining, digging, loading and transporting in the underground, because of the difference of working environment, the spray dust reduction technology has their own different characteristics. In addition to the random mining (coal mining machine and roadheader) spray, Other shipping, reprinting and purifying romantic occasions to be taken to spray sprinkling measures collectively referred to as “fixed-point spray.” This article discusses only some of the technical issues with spot spray.
