water-jet channeling

Water-jet channeling is a technique used in quarrying and mining to cut channels in stone. This method involves using high-pressure jets of water, sometimes with an abrasive substance, forced through a small nozzle at high velocity. This process creates new cracks and penetrates existing ones, slicing away thin layers of rock.1

The advantages of water-jet channeling include cutting narrow, straight channels with minimal noise and without damaging the surrounding rock surfaces. This technique is an alternative to traditional methods like wire saws or mechanical drilling for separating stone from its parent mass.1
