# Research Progress on the Mechanisms and Control Methods of Rockbursts under Water-Rock Interactions
## 4 Consideration of Water's Impact on Rockburst Prediction and Prevention
### Consider the Prevention and Control of Water-Affected Rockbursts  
In coal mining, preventing rock bursts is often closely tied to managing water conditions. Techniques such as large-diameter drilling and water injection are employed to alleviate high-stress concentrations, reduce the strength of the coal mass, and diminish the risk of rock bursts. Hydraulic cutting technology utilizes a high-pressure liquid to achieve the cutting of materials. The basic principle is that the liquid (usually water) is pressurized to an extremely high level by means of a hydraulic pump, and then the high-pressure liquid is ejected through a fine nozzle. This technique enables cutting to be carried out without generating high temperatures and therefore does not result in thermal deformation or hardening of the material. A common form of hydraulic cutting is high-pressure waterjet (HPW), while waterjet with added abrasives (AWJ) is suitable for harder materials.  
When stress concentrations are not effectively managed, strong disturbance stress blasting may be utilized to address the issue [79; 80]. [PERSON] et al. [81] proposed a strategy involving the arrangement of small panels and large coal pillars to facilitate pressure relief and prevent rock bursts. This method aims to strategically distribute stress and mitigate the conditions that lead to rock bursts. [PERSON] et al. [82] demonstrated that hydraulic cutting is effective in reducing and redistributing stress concentrations within the coal seam. This approach also lessens the potential impact on the coal rock mass, thereby significantly lowering the probability of coal rock bursts. Large-diameter drilling technology is mainly used to excavate large-diameter holes in rock, soil, and other geological conditions, and is widely used in tunneling, foundation construction, and oil and gas drilling. This technology usually uses automated drilling equipment, which can efficiently complete the excavation of large-volume holes.  
In conclusion, the impact of water on rock bursts is a complex issue that requires detailed analysis and assessment based on specific conditions. Future research should further explore the mechanisms by which water influences the development trends of rock bursts in various environments and propose corresponding prevention and control measures. For instance, in underground mining, reducing groundwater levels, strengthening support systems, and enhancing drainage can help mitigate the effects of water on rock bursts. In natural disaster scenarios, improving the seismic resilience of buildings and infrastructure, and planning urban and transportation systems more effectively, can reduce the occurrence of rock burst incidents. Specific measures are set out below:  
1. Hydraulic fracturing and pressure-relief water injection. Hydraulic fracturing creates fissures in the rock body by injecting high-pressure water, releasing stress, slowing down stress concentration, and reducing the risk of rock explosion. Bucking water injection makes the stress release smoother by reducing the initial stress in the rock body, which is suitable for high-risk areas with stress concentration.  
2. Rock softening and wet blasting. Water injection is used to soften the rock, reduce its strength and brittleness, thereby reducing the energy release during the rupture, to prevent rock burst. Wet blasting uses water to reduce the temperature and stress concentration during blasting, mitigating the risk of rock explosion generated during blasting.
3. Groundwater drainage and water curtain spraying. A drainage system is used to control the accumulation of groundwater, reduce the water content of the rock mass, and improve its stability. Water curtain spraying by reducing the surface temperature of the rock body and friction in the fissure, effectively preventing the rock explosion caused by temperature changes, is suitable for high-temperature stress environments.
