- 저폭속폭약을 이용한 발파방법에 있어서발파공을 천공한 후 저폭속폭약을 특수한 이중의 장약통과 결합하여 각각의 발파공에 장전하고, 전기 및 비전기 뇌관을 사용하여 순발 및 지발로 발파하여 일차적으로 저폭속폭약에서 발생하는 낮은 폭발충격파와 이차적으로 이중의 공기층을 통과하면서 폭압이 더욱 감소됨으로써 진동의 크기를 대폭 낮추고 천공과 천공 사이에 인장균열을 발생시키는 발파 방법을 특징으로 하는 저폭속폭약을 이용한 미진동 발파방법.
- 제1항에 있어서 저폭속폭약이 천공내 중앙에 위치하고 전색물이 폭약의 상부에만 위치하게 하여 천공과 저폭속폭약 사이에 공간을 형성하는 것을 특징으로 하는 저폭속폭약을 이용한 미진동 발파방법.
