USING THE OSCILLATING DIPOLES MODEL TO STUDY THE ELECTROMAGNETIC RADIATION INDUCED BY FRACTURE OF ROCKS

By Z. Chen and K.-M. Huang

Abstract:
In this paper, we make an assumption that the inertia vibrations of the electron groups in the rock fragment of the crack tips generate EMR pulses during the fracture of rocks. Based on this assumption we develop an oscillating dipoles model to analyze and simulate the EMR phenomena induced by the rock fractures. Then we use this model to simulate the EMR pulses recorded in the Rabinovitch's compression experiments on granite and chalk. Our simulations indicate a comparable accordance with Rabinovitch's experimental results. From our simulation results, we also find that the crack width associates with the maximum EMR voltage peak value.
