实施光面爆破,不仅减小了爆破对围岩的破坏,有利于保持围岩的稳定,而且还可以避免欠挖和超挖,有利于开挖作业的安排,并能取得较好的开挖轮廓和提高壁面平整度,减少水流或气流的摩阻损失。因此,在地下工程的开挖中,光面爆破技术得到了越来越广泛的应 The implementation of smooth blasting not only reduces the destruction of the surrounding rock by blasting, is conducive to maintaining the stability of the surrounding rock, but also avoids under-digging and over-digging, is conducive to the excavation operation arrangement, and can achieve better excavation Contour and improve wall flatness, reduce water or air flow friction loss. Therefore, in underground engineering excavation, smooth blasting technology has been more and more widely applied
