Experimental Study of Influence of Support Failures on Rockbursts under True-Triaxial Condition

Figure 19

The rockburst process of the tested specimen under different support failure rates (the numbers at bottom-left corner of the pictures indicate the time in h:m:s.ms): (a)  = 0.5 MPa/s; (b)  = 1.0 MPa/s; (c)  = 2.0 MPa/s.
