摘要
张坝沟石灰石矿长期采用传统光面爆破技术来减小爆破震动及后冲对永久边坡的危害,但是传统光面爆破存在大量的缺陷,需要找到一种更优越的光面爆破方法来保证永久边坡的稳定性。文中较详细地介绍了爆轰波在爆破破岩中的作用,根据其破岩机理提出了几种新的更优越的光面爆破方法。
Traditional smooth blasting to decreasing blasting vibration and back impact for breakage of final slide-slope is used in Zhang Bagou-limestone quarry, but traditional smooth blasting has much limitation. The better smooth blasting of requiring discovery ensures stability of final slideslope. Effect of detonation wave in rock fragmentation is detailedly introduced several new smooth blasting methods are brougth forward according to its mechanism of rock fragmentation in this paper.
