结合岩石强度理论和岩石损伤破坏机理,分析刀具切削破岩机理,基于刀具与岩土相互作用的受力情况,分析刀具适用的地质条件,进而对掘进机刀盘刀具进行选型布置,为掘进机刀盘设计提供理论参考。
Based on the theory of rock strength and the damage mechanism of rock damage, the mechanism of cutting rock breaking is analyzed. Based on the interaction between cutting tool and rock and soil, the geological conditions of cutting tool are analyzed. Then the cutting tool of heading machine is selected and arranged. Machine cutter design provides a theoretical reference.
