Explosion-Induced Stress Wave Propagation in Interacting Fault System: Numerical Modeling and Implications for Chaoyang Coal Mine

Figure 7

The evolution and attenuation of stress in the XX direction (Sxx, MPa) recorded at six passive particles (indicated by the black and red points, faults A and B are shown by the purple lines) influenced by the stress wave. Panel (d) is a cross section extracted in the middle of the model box (Figure 1). The Y-axis represents Sxx (MPa), and the X-axis is the duration of running model. ΔSxx is used to show the difference of the first and/or second waves’ amplitude (orange dotted line), which could help indicate the attenuation degree due to the absorption or resistance effect of weak faults.
