一、用途瑞典 Atlas Copco 公司生产了一种小型全断面掘进机,它主要是用来掘进安放水管、气管、电缆和通讯管线的燧道,以代替打眼、放炮法,这在人口稠密的地方和市区,是十分必要的。它还可以用来打大直径孔的超前孔,打通风巷道和探矿巷道等。二、工作原理这种小型全断面掘进机应用了已经获得专利的底切法,即切割岩石与破碎岩石相结合的掘进方法。在每个工作循环中,刀盘从最初向下的位置,绕与巷道轴线成90°的水平轴转动
A Use Swedish Atlas Copco company produced a small full-face boring machine, it is mainly used for driving water pipes, trachea, cables and communication lines of tunnel instead of drilling, blasting method, which in densely populated areas and Urban area is very necessary. It can also be used to play large diameter hole ahead of the hole, playing ventilation roadway and prospecting roadway. Second, the working principle of this small full-face boring machine has been applied patented undercutting method, that is, cutting rock and broken rock drilling method combined. In each working cycle, the cutter head is rotated from the initial downward position about a horizontal axis 90 ° to the lane axis
