Table 4

Field monitoring data of blasting vibrations.

The total explosives (kg)	The maximum charge of one section (kg)	Sections	The distance from explosion source (m)	PPV (cm/s)
				X	Y	Z
432	150	5,6,7	130	0.15	0.13	0.10

Note. X was the horizontal direction pointing to the explosion source, Y was the horizontal direction perpendicular to X, and Z was the vertical direction.
