Insights into the radial water jet drilling technology – Application in a quarry
Journal of Rock Mechanics and Geotechnical Engineering, 2018 In this context, we applied the radial water jet drilling (RJD) technology to drill five horizontal holes into a quarry wall of the Gildehaus quarry close to Bad Bentheim, Germany. For testing the state-of-the-art jetting technology, a jetting experiment
