There was layered recrushing phenomenon in the compression process of crushed limestone. Comparing the quantity and energy level of 3D AE location events in each layer, we discovered that the recrushing behaviour in the middle layer was the most active, and that in the upper layer was approximately twice than that in the lower layer.
