ROCK BLASTING METHOD HAVING NO-NOISE AND NO-VIBRATION

摘要

The present invention comprises the steps of drilling a hole (2) with a predetermined diameter (D) and depth (H) in the rock (1), installing a gunpowder (3) and a primer (4) at the bottom of the hole (2), explosives Filling the earth and sand (5) to a certain depth above, filling up to the top of the hole (2) with a curable resin solution (6) to absorb vibrations and noises during blasting, and connected to the primer (4) of the gunpowder (3) It relates to a vibration-free and noise-free rock blasting method characterized by consisting of a rock crushing step of exploding the gunpowder (3) by crushing the rock (1) by applying an electric current to the wire (7).
