摘要
某露天铁矿东北帮受周边爆破影响,在边坡布置2条测线测试振动速度,采用萨道夫斯基公式对测得的数据进行拟合回归方程预测,最终得到300°、285°方向以及-30 m平台处的萨道夫斯基公式,将-30 m平台处回归数据和实测数据进行对比,得出实际振速比回归预测振速略高,通过增加测点及测试次数可以减小误差。结果为今后边坡爆破测振提供理论依据。
The northeast of a open-pit iron mine is affected by its periphery blasting, two measure- ment lines are set in the slope of the mine to monitor the vibration velocity, the monitoring data is fitted regression analysis to predict by Sadov＇s formula, the Sadov＇s formulss of the directions of 300°,285°and -30 m level plafform are obtained. The comparison of the regression analysis data and actual measured data of -30 m level plafform is done, the results show that, the actual vibration velocity is higher than the one acquired by regress prediction, through increasing monitoring points and test times, the prediction error of blasting vibration velocity can be decreased. The above discussion results can provide some theo- retical basis for the monitoring of blasting vibration velocity.
