| 摘 要： | 研究了爆破振动对石灰岩矿山边坡的影响，通过现场爆破振动测试，结合现场地质条件进行了爆破振动特性及规律研究。结果表明，基于M.A萨道夫斯基拟合公式的2次现场爆破振动数据中质点振动速度具有明显的衰减趋势；基于高程效应修正的M.A萨道夫斯基拟合公式的相关系数达到了0.94,比传统M.A萨道夫斯基公式拟合效果好；采用本文得到的修正拟合公式，结合靠帮设计起爆药量，对石灰岩边坡各台阶最大振动速度进行预测时发现，爆破设计应重点考虑振源临近台阶造成的影响。

| Abstract: | The impact of blasting vibration on the open-pit slope in a limestone mine was explored. The characteristics and law of blasting vibration was investigated by performing field blasting vibration tests based on the consideration of geological conditions on site. Based on fitting with Sadowski formula, an obvious attenuation trend was found for the velocity of particle vibration in the data about two field blasting vibration. With Sadowski formula modified based on elevation effect, the correlation coefficient was up to 0.94, better than the fitting effect by the traditional Sadowski formula. The maximum vibration velocity on each bench of limestone slope was predicted by using the modified fitting formula in this paper, and considering the designed detonate charge for steep end-slope, showing that the impact of vibration source on the adjacent bench should be taken into consideration in blast design. |
