一、引言喷雾灭尘是一种简便有效而又经济的灭尘措施,在全断面岩巷掘进机上也得到了广泛应用。喷雾灭尘效果的优劣对掘进头岩尘浓度的高低有很大影响。灭尘效果主要取决于喷咀的性能和布置方式,一定的水压和足够的水量。本文拟从岩尘的产生过程和喷雾灭尘的机理方而谈谈一些粗浅的见解。二、岩尘的产生过程全断面岩巷掘进机工作机构上使用的截割装置是盘形滚刀。工作时,盘形滚刀以强大的推力压向岩石,刀刃下方的岩石首先被压碎,成粉末状,我们称这个区域为粉末
First, the introduction Spray dust is a simple and effective and economical dust control measures, full-face rock tunnel boring machine has also been widely used. Spray dust effect on the quality of rock dust driving head has a great impact on the level of concentration. Dust removal effect depends mainly on the nozzle performance and layout, a certain amount of water pressure and water. This article intends to talk about some superficial opinions from the process of rock dust generation and the mechanism of dust spray. Second, the rock dust generation process Full-face rock tunnel boring machine working mechanism used on the cutting device is disc-shaped hob. During work, the disc-shaped hob pressed against the rock with a strong thrust. The rock beneath the blade was first crushed to powder, which we call the powder
