Experimental Study on the Blasting Droping - vibration of Impacting the Ground
Jinquan Zhang · Blasting · 2003
Impacting on ground through heavy hammer is used to simulate the shaking - ground of the blasting target droping - vibration to obtain the frequency characteristic of focus of the droping - vibration of ground, the change in the course of propagating of the seismic wave , and the hardness of place to the influence of decaying the droping- viberation of ground.
