Contour Cutting Mechanisms as a Means of Improving Underground Stability
Szwilski A. B. and Brawner, C. O.
The advent of high pressure waterjets gives the potential for creating a slot around the perimeter of the opening such that the central core can be removed more rapidly, either by high pressure waterjet impact or conventional blasting, without the problems associated with current blast practice. Because of the small size of the unit required and the degree of mobility achievable with robotic control of the lance, the range of application of this new technology is sizeable.
