Construction Vibration Damage Guide
The perception of blast vibration is further complicated by the presence of ground vibration and air vibration, which separate with distance because of the different propagation velocities. Both air and ground vibration are commonly perceived by secondary noise, such as rattling of dishes, windows or sliding doors, and without monitoring it may not be possible to recognize whether air or

The vibration level at a distance depends on charge per delay, vibration frequency, rock characteristics (type, unit weight, layering, slope of layers), blast hole conditions, presence of water, propagation of surface and body waves in the ground, and to a lesser extent on method of initiation. Fractures are developed in rocks due to tensile and shear stresses. Hence, studies of blast-induced
