Experiment of Rock Fragmentation by Cutting Blades with An Attack Angle

摘要:

介绍了刃具斜切入破岩的试验装置及试验结果，推导出了跃进载荷的计算公式，并对试验结果进行了理论分析，探讨了影响刃具侵入岩石难易的因素和影响破岩比功大小的因素。

Abstract:

he testing device used in rock fragmentation by cutting blades with an attack angle is describedwith the testing results. The leap-load calculation formula is derived' A theoretical analysis is conducted on thetesting results. The factors influencing the difficulty of the cutting blades penetrating rock and those influencingthe level of rock fragmentation specific energy are explored.
