摘要
瘦高型山体整体定向爆破,采用定向滑落爆破技术,应是一项安全、经济的好方法。该技术是在需爆破山体的下方,用松动爆破的原理,爆出一个有一定高度和坡度的“滑落带”,受坡面斜度的影响,就会带动上面的山峰向预定方向滑落,并在滑落过程中摔动达到破碎效果。本文结合实际工程,阐述了滑落山体斜面倾角的确定、爆破参数的选择,确保了该技术取得成功。
The technology of directional slide blasting is a safe and economical method for directional blasting of slim mountain to reach a whole demolition. The＂Directional Slide Blasting＂in this paper was used for creating a＂slide zone＂with a certain extent of grade and height underneath the mountain based on loose blasting theory. The grade of the＂slide zone＂drove the mountain above it to slide along the anticipated direction,and hence the mountain body collapsed into pieces. The paper gave some information in detail on the determination of inclining angle of＂slide zone＂and the blasting parameters for the success in the blasting demolition of the mountain.
