# Research Progress on the Mechanisms and Control Methods of Rockbursts under Water-Rock Interactions
## 5 Conclusions  
The mechanical properties of rocks and their influence on rock burst phenomena have been a central topic in geotechnical engineering for many years. Recent studies have increasingly underscored the substantial effects of moisture on rock mechanics. This paper examines how water affects rock mechanical properties and rock burst behavior, summarizing methods and experimental advancements related to the water-induced weakening of rock bursts. The key conclusions are as follows:  
1. Water's weakening effects: Water notably weakens the mechanical properties of rocks through both physical and chemical mechanisms. It accelerates the breakdown of the rock's microstructure, enhances the development and propagation of microcracks, and decreases the rock's strength and stiffness. Moreover, water reduces the rock's elastic strain energy storage, increases energy dissipation, and hinders the concentrated release of elastic strain energy, thereby lessening the severity of rock failure.
2. Reduction in rock burst risk: Water reduces the likelihood and severity of rock bursts by weakening the rock's mechanical properties and diminishing its energy storage capacity. Practical engineering strategies, including water injection into the surrounding rock, high-pressure water spraying, and hydraulic cutting, are used to mitigate the risk of rock bursts.
3. Considerations for rock burst testing: When performing rock burst experiments, it is crucial to consider how different types and amounts of water affect rock mechanical properties and test outcomes. In high-pressure rock burst tests, the influence of water on compressive strength, dynamic strength, and fracture patterns should be carefully evaluated. Addressing the impact of moisture comprehensively and exploring prediction and control methods under various interacting conditions can offer valuable insights for practical applications in geotechnical engineering.  
In summary, ongoing research into the effects of moisture on rock mechanical properties and rock burst testing enables more accurate simulation of real-world conditions, improves the reliability of experimental outcomes, and provides valuable insights for practical applications in geotechnical engineering.
