【 摘 要 】

Blasting vibration signals are the comprehensive embodiment of the blasting seismic waves with the effects of the field medium. They can reflect the characteristics of the blasting source to a certain extent. At the same time, they can reflect the features of the field medium. Motivated by this fact, this paper applies generalized dimension based on morphological covering (MC) method to characterize the nonlinearity and complexity of the blasting vibration signals. We establish the fractal dimension model according to the propagation laws and features of the signals. Based on the test data measured from rock field, the generalized dimension of the signals is calculated. Experimental results reveal that the generalized dimension of blasting vibration signals reflect the feature information of the propagation medium in the blasting field. The generalized dimension based on MC method can be regarded as a new parameter to describe the blasting vibration signal and lay the foundation for establishing a more effective prediction model of blasting vibration.
