Abstract
A non-oscillatory rock cutting apparatus using hydraulic pressure and a method of controlling hydraulic pressure of the same. At least one element producing expansion pressure from pressure of a fed fluid is installed in a hole drilled in rock such that the expansion pressure is applied to the drilled hole by the pressure of the fed fluid. The element includes an internal tube, which encloses the outer circumference of a hydraulic pressure supply pipe, an external tube, which is located around an outer circumference of the internal tube so as to cover at least part of the internal tube, and a fixing unit, which supports the external tube and the internal tube on the hydraulic pressure supply pipe toward opposite ends of the external tube. Thereby, the non- oscillatory rock cutting apparatus using hydraulic pressure expands the internal tube using the pressure of the fluid, thereby cutting the rock without oscillation.
