Abstract

Based on experimental and in-situ tests, the propagation and attenuation rules of seismic wave in the intact and jointed rocks subjected to conventional triaxial loading condition were investigated, especially the influencing effects of joints and beddings on the attenuation. Meanwhile, the frequency-spectrum evolutions during the process of attenuation were analysed in detail. To verify the outcomes obtained from the laboratory, the attenuation characteristics of seismic wave generated by blasting in underground strata were tested, and the attenuation rules by the joints between strata was summarized. Finally, the seismic response of joints and beddings in rocks was revealed. This work put forward some references for early weakening and controlling coal-rock dynamic disasters triggered by seismic wave in coal mines based on the attenuation effect of artificial discontinuity such as joint and bedding.
