  Kerf Depth with Abrasive Waterjet Power for Hard Rock Cutting

  Abstract: Abrasive waterjet cutting technology is used for rock tunnelling and mining because the process is eco-friendly. To estimate precisely the waterjet operating time and cost, it is important to verify the kerf depth generated by the power of the abrasive waterjet power (e.g., water pressure, water flow rate, or traverse speed). In this study, rock excavation using an abrasive waterjet cutting...

  The Kinetic Energy of Abrasive Particles Considering Specific Gravity in Waterjet Rock Cutting

  Abstract: Waterjet technology has been increasingly applied to civil engineering such as rock excavation or concrete demolition from its various advantages. However, recent performance studies, based on the complex influence of the waterjet systems, lack sufficient theoretical approaches to be adequately applied to civil engineering. In particular, research on the particle kinetic energy is important for...
