Abstract: Under the complex stress environment of three high and one disturbance, severe deformation and failure of surrounding rock occur frequently in dynamic pressure roadway in deep coal mines. The attenuation characteristics of dynamic waves differ in various media, which provides a feasible insight for roadway stability control. In this paper, the propagation process and strength attenuation characteristics of dynamic waves were investigated by using the UDEC discrete element method. On this basis, the strength attenuation and energy dissipation of dynamic waves during propagation were investigated based on the rock dynamics theory. It was found that as the propagation distance and attenuation factor increase, and the transmission rate decreases, both the strength attenuation and energy dissipation increase in different degrees. Notably, the significant interface effect occurred in the intact-fissure combined rock mass. The strength attenuates sharply, whereas energy dissipation increases greatly. Then, the anchored rock slipping model under static-dynamic loads was established, and the anchored rock fracture inhibition mechanism considering the supporting efficiency coefficient was revealed. Moreover, a homogenization equivalent model of anchorage cone was established based on the homogenization theory. The reinforcement effect of the supporting structure was mapped to the entire anchored rock mass, and the equivalent deformation modulus was obtained. On this basis, the relationship of opposites and unity between the support reinforcement effect and the fracture inhibition mechanism on the strength attenuation and energy dissipation was discussed. A synergistic dynamic resistance mechanism for anchored surrounding rock was proposed. When the output strength and residual energy of dynamic wave through the anchored rock mass are 0, the dynamic pressure roadway remain stability. Finally, an supporting optimization design method for dynamic resistance was proposed, which aims to achieve optimal synergistic dynamic resistance effect by designing supporting parameters such as the material, cross-section, length, and spacing. In-site practice was applied in the 6305 haulage roadway of the Xinjulong Coal Mine. Results showed that the maximum roof-to-floor convergence and two-sides displacement were 125.0 mm and 76.0 mm, respectively, and no dynamic phenomena were observed, which has achieved good application effect. This study could provide guidance and reference for dynamic disasters prevention and stability control for dynamic pressure roadway in deep coal mines.
