Abstract: Fault-slip induced rockburst poses a serious threat to safe and efficient mining in deep coal mines, and it is of great significance to investigate the control factors and essential mechanisms of fault-slip induced roadway rockburst damage for disaster prevention and control. Based on the self-developed coal mine roadway fault-slip rockburst test system, we developed low-strength and high-brittle model materials and prepared a physical model of fault-slip roadway rockburst, proposed a loading method for fault slip, successfully reproduced the geologic disaster phenomenon in the whole process of fault-slip induced roadway rockburst damage, and supplemented with numerical simulation to reveal the mechanism of fault-slip roadway rockburst. Key findings include: ① The low-strength and high-brittleness similitude material, formulated with sodium silicate as the primary binder, exhibits an average uniaxial compressive strength of 7.40 MPa, cohesion of 3.35 MPa, rockburst energy index of 18, and elastic energy index of 9.2. Under uniaxial loading, it demonstrates dynamic failure behaviors such as elastic ejection and debris spalling, effectively replicating fault-slip induced roadway rockburst scenarios. ② By adopting the scheme of “critical loading of the roadway first and activating loading of the fault”, the simulation of the whole process of fault-slip rockburst in roadways was realized. The fault-slip process has significant stick-slip characteristics, corresponding to intermittent rockburst damage of the roadway, and the rockburst damage process is extremely short. The ejection of small particles from the roadway gang is a significant precursor feature of the rockburst damage of the roadway. ③ The mechanism of the whole process of fault-slip induced roadway rockburst is as follows: the fault in the process of shearing, the locking structure of the gradual rupture to stimulate the seismic wave - the seismic wave is propagated to the surrounding rock of the roadway in an attenuated manner - the seismic wave induces the high stress of the surrounding rock of the roadway to release the strain energy and rockburst damage occurs. ④ The seismic wave excited by fault slip is the direct trigger factor of the fault-slip rockburst in roadways. The main energy of the fault-slip rockburst in roadways comes from the strain energy released by the surrounding rock of the roadway, of which 30% is transformed into sliding friction energy, which is used for fissure expansion to make the rock body broken, and 5.6% is transformed into kinetic energy, which induces the crushed block is ejected and rushed out.
