基于修正的萨氏公式对广东大旺塘矿山爆破震动的安全性评估

Safety assessment of the Guangdong Dawangtong Mine blasting vibration based on the modified Sa's formula

本文以广东大旺塘矿山为例,采用修正的萨氏公式对矿山开采爆破产生的震动进行了安全性评估.对系统测定的爆破震动数据,分垂直速度和水平速度两种情况进行二元线性回归.对萨氏公式作了修正,建立了大旺塘矿区的经验公式,并提出了安全生产的建议.

Taking Dawangtang stope for example, the safety assessment of mine blasting vibration using the mod- ified Sa＇ s formula was evaluated. The binary linear regression method in both vertical and horizontal speeds was used to analyze the data measured from blasting vibration. The Sa＇ s formula was modified and an empirical for- mula of Dawangtang stope was established. Also a suggestion of safety was proposed.
