Excavation Method of Reducing Blasting Vibration in Complicated Geological Conditions

Table 1

The comparison of vibration peak between the measured and numerical simulation results in Fengning site test.

Number of the measured points	Charge; (kg)	Distance from blasting source	Measured vibration peak
			Vertical direction		Horizontal radial
			Measured value; (cm/s)	Numerical simulation value (cm/s)	Measured value; (cm/s)	Numerical simulation value (cm/s)
