摘要
某露天采石场距相邻村庄最近建筑仅100m,为避免爆破振动对建筑和村民的生活造成影响,采用毫秒微差爆破技术减小爆破振动。微差间隔时间为50ms,将爆破振动速度控制在0.7cm·s-1以下,保证了工程的安全顺利实施。
An open-pit quarry is only 100 m from the nearest building in the neighboring village. To avoid the impact of blasting vibrations on the villagers’ everyday life and buildings, millisecond blasting technique was applied. The delay time was set to 50 ms, and the blasting vibration speed was controlled below 0.7 cm/s. Therefore, the project could be implemented safely and smoothly until the end.
