Observation and Analysis of Blasting Vibration to the High Slope of Jinduicheng Open-pit Mine

Through blasting vibration tests and field monitoring,some characteristics about the velocity of blasting vibration,the main frequency character of blasting vibration and duration of blasting vibration were obtained.The author concluded the blasting vibration propagation and attenuation regularity about four side slopes in the Jinduicheng open-pit mine.The binary linear regress analyzing principle is used to analyze the amplification effect about blasting vibration,moreover,the results are compared with those using unary linear regressive analyzing principle.Combined the practics in open mine,some effective measures were advanced to protect the slope.
