滚刀破碎岩石滚刀破碎岩石rock breaking with rolling diskgUndoo印su}yonshl滚刀破碎岩石(roek breaking with rolling di-sk)用带刃的盘形滚动工具破碎岩石的凿岩方法。它是岩石掘进机或天井钻机破碎较硬岩石的一种基本方法。滚刀在巨大的正压力作用下在岩石表面滚动，岩石在滚刀的碾压下破碎。滚刀的结构坚固，破岩效率较高，不易磨损，是大断面机械破碎硬岩的常用工具。滚刀直径40。一50() mm，刃角约60。，每把滚刀上施加的正压力视岩石而定，约为50一ZookN。牵引力一般是正压力的1/l。一1/15。滚刀滚动的线速度在Zm/s以下。滚刀一般用高强度耐磨合金钢制造，有时也嵌有硬质合金齿。依据掘进断面的大小，常采用几把甚至几十把滚刀同时工作。各滚刀的压痕呈同心圆状分布，相互间的距离视岩石性质而定，以最省能耗为度。在边缘部分的滚刀负担最重，应增加其数目。
