| 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. |
