摘要：
In order to study the fractal characteristic of blasting seismic wave, the box-dimension model was established based on the fractal theory. In this model, the characteristic and propagation rule of blasting seismic wave were considered. By using the test data of the deep-hole blasting experiments carried out at a rock site, the fractal box-dimension values D of blasting seismic signals were calculated according to this model. By analyzing the mathematical meaning of box-dimension values D and its relationship with medium characteristic, the fractal mechanism of blasting seismic wave was discussed. The result indicates that fractal box-dimension value D of the blasting seismic wave can reflect the rock characteristic information of blasting seismic wave's propagation medium. So it can be used as an important new parameter to describe the blasting seismic wave. In this way, the box-dimension research of blasting seismic wave lays a foundation to design more effective blasting vibration response forecast models.
