Investigation of the artifical vibration wave motions formed on the dry and saturated rock samples

Blast-induced vibration waves can expand far away from its resource. According to its strength it has a capacity to damage civil structures. It is therefore critical that wave propagation mechanism of each mine site should be well presented and its neutralization facts are described. In this study, vibration wave result from blasting of mining and tunnel excavation site were simulated in laboratory by impact wave initiator. Vibration propagation based on the change of peak particle velocity in dry and saturated rock samples were then determined to compare. Vibration monitoring seismograph were used to measure and record the waves farm (transverse, longitudinal, vertical and peak vector sum) at the predetermined point on rock samples. Under constant distance between vibration wave initiator and vibration measuring device, differences in waves were evaluated by the rock porosity and water content.
