摘要
A rock cutting apparatus includes a shaft having a hollow therein where high-pressure water is movable, the shaft being configured to be inserted into a hole, a moving unit for forcing the shaft to reciprocate, and a nozzle unit installed at a front end of the shaft to inject the high-pressure water moving through the shaft. The nozzle unit injects the high-pressure water to cut a rock around the hole so that the hole communicates with a neighboring hole. Therefore, a cut surface or line is formed before blasting, which reduces blasting vibration transferred to the outside and minimizes overbreak.
