小官庄铁矿巷道掘进爆破地震波传播特性研究

Blasting seismic wave propagation law research in drivage in Xiaoguanzhuang Iron Mine

以巷道掘进爆破为研究对象,基于撒道夫斯基公式对爆破地震波传播规律进行研究。监测结果显示最大振动速度为0.39cm/s,质点峰值振动速度随爆源距的增加呈指数衰减趋势。拟合结果相关系数达到0.97,相关度高,所得公式可为巷道掘进爆破装药量及安全距离的设计提供参考。

Drivage blasting seismic wave propagation law was studied based on the formula of Sadowski.The monitoring results showed that the biggest vibration velocity was 0.39cm/s,and the particle peak vibration velocity decayed exponentially with the increase of the distance.The Fitting correlation coefficient is 0.97 which is a high correlation.The formula provided effective references for the design of maximum charge and the safe distance in drivage blasting.
