Hard rock tunnel boring machine penetration test as an indicator of chipping process efficiency
The transition from grinding to chipping can be observed in tunnel boring machine (TBM) penetration test data by plotting the penetration rate (distance/revolution) against the net cutter thrust (force per cutter) over the full range of penetration rates in the test. Correlating penetration test dat...
