- AWJ rock drilling technic has been suggested for the auxiliary/alternative drilling method
- Waterjet performance according to the energy parameter (SOD, Water pressure, Abrasive feed rate, etc.) has been studied
- Optimal operational parameter has been explored

Abrasive Waterjet Application in TBMs

- Enables high-efficiency in TBM cutting with over cutting method
- Novel method with Waterjet Aided Excavation
- Waterjet aided disk cutting efficiency has been tested using numerical analysis (UDEC)

Garnet Abrasive Recycling in AWJ application

- Changes in the particle characteristics (particle size distribution, particle shape, and mean particle size) of garnet abrasives were analyzed after the drilling performance
- Overall, recycling rate of used abrasives was determined based on the particle characteristics
