# Research Progress on the Mechanisms and Control Methods of Rockbursts under Water-Rock Interactions
###### Abstract  
Rock bursts are among the most severe and unpredictable hazards encountered in deep rock engineering, posing substantial threats to both construction safety and project progress. This study provides a comprehensive investigation into how moisture infiltration influences the propensity for rock bursts, aiming to establish new theoretical foundations and practical methods for their prevention. Through the analysis of meticulous laboratory mechanical experiments and sophisticated numerical simulations, we analyzed the variations in the physical and mechanical properties of rocks under different moisture conditions, with a particular focus on strength, brittleness, and energy release characteristics. The findings reveal that moisture infiltration significantly diminishes rock strength and reduces the likelihood of brittle fractures, thereby effectively mitigating the risk of rock bursts. Additionally, further research indicates that in high-moisture environments, the marked reduction in rock burst tendency is attributed to increased rock toughness and the suppression of crack propagation. This study advocates for the implementation of moisture control measures as a pre-treatment strategy for deep rock masses. This innovative approach presents a viable and effective solution to enhance engineering safety and improve construction efficiency, offering a practical method for managing rock burst risks in challenging environments. rockburst; hydro-rock interaction; water-induced rockburst weakening; rockburst prevention and control +

Their findings revealed that rockbursts could happen at any stage of the blasting cycle, with the highest frequency occurring during hazard elimination and support phases, and the lowest frequency during drilling and loading phases. [PERSON] et al. [1] carried out simulation tests of slab cracking damage in different arch structures and found that 1/4 three-centered arches were safer and more economical than 1/3 three-centered arches and semicircular arches. [PERSON] et al. [17] carried out a series of uniaxial compression tests on columnar granite specimens containing circular apertures (apertures with radii ranging from 20 to 103 mm) to study the effect of aperture dimensions on the damage to the wall and pointed out that the field tunnel apertures were not affected by scale effects. wall slab cracking is not affected by scale effects. [PERSON] et al. [18] conducted two types of rockburst experiments--strain burst and impact-induced rockburst--using a strain burst device equipped with an acoustic emission (AE) monitoring system and an impact-induced rockburst setup, under varying initial geological stresses. The findings revealed that the rockburst process was consistent across different initial stresses, with the intensity of rockbursts increasing as the initial in situ stress rose. [PERSON] et al. [11] investigated circular tunnels' damage process and evolution mechanism under complex stress paths, including in situ stress, excavation unloading, and stress redistribution. The results revealed that, within a certain range of in situ stress, the support of surrounding rock plays a more significant role in reducing damage risk and severity compared to unloading methods in deep underground projects. [PERSON] et al. [19] found that at moderate depths, the stress damage zone only appears in a localized area around the tunnel, whereas at greater depths, the stress damage zone will extend along the entire tunnel excavation boundary. [PERSON] et al. [20] showed that with increasing depths, the stress-induced damage can be transformed from a surface spalling to an intense rockburst. [PERSON] et al. [21, 22] investigated the rockburst characteristics of basalt and granite, identifying the influence mechanisms of liner angle and unloading rate using uniaxial compression and triaxial unloading compression tests.
