# A Comprehensive Review of Mechanisms, Predictive Techniques, and Control Strategies of Rockburst
## 6 Rockburst Prevention and Control  
The significance of rockburst incidents has led engineers and academics to focus on rockburst prevention and control strategies. [PERSON] detailed the procedures for rockburst prevention at the Jinping II Hydropower Station, which effectively prevented rockbursts by reducing the surrounding rock stress and weakening excavation disturbance [179]. The presence of foliations in the rock mass at Big Bell, Australia, influences both the magnitude of high stress and deviatoric stress. Mining is concentrated in a central slot in the orebody that spans a larger 350 m section. This, however, can cause strain and pillar bursts. Destress blasting, which involves developing the football and decline, is used to mitigate this hazard. This is accomplished by drilling two 4.2 m holes at 45\({}^{\circ}\) angles from the top corners and filling each with 700 mm packaged emulsion [180; 181; 182]. Another rockburst event occurred at Australia's Long Shaft, which is located in a high horizontal stress field. The rock mass here is made up of a complex of varying strength units. The orebody has a strength of 140 MPa, while the football has a strength of 275 MPa. The hanging wall, on the other hand, has a pressure range of 75 to 250 MPa. A variety of events, such as fault-slip, strain, and pillar bursts, can occur as a result of these opposing strengths. Effective dynamic support is used to mitigate these risks. Mesh-reinforced shotcrete, yielding tendon bolts, fiber (steel)-reinforced shotcrete, friction bolts, mesh, and mesh straps are examples of such measures [183]. According to [PERSON], the primary cause of rockbursts in an uneven working face is the combined dynamic and static strain, which led to the development of a suitable control method to reduce dynamic load through directional hydraulic fracture and improve the surrounding rock through a support system [184]. [PERSON] highlighted several solutions used in Canada to reduce the risk of rockbursts in deep mines, arguing that with increasing mine depth, widespread construction of a support system with dynamic load-bearing capability may become necessary [185]. [PERSON] outlined rockburst pretreatment methods such as blasting, decompression drilling, and hydraulic fracturing and presented rockburst support experience from Australia, Canada, and South Africa [186].

summarizes the main rockburst prevention and control strategies used in several mines and tunnels.  
To prevent rockbursts, researchers and engineers have long focused on excavation support techniques. Laurentian University's Rock Mechanics Research Center conducted a five-year research project on rockburst control, resulting in the creation of the _Canadian Rockburst Support Handbook_. The handbook outlines the causes and features of rockburst failure and provides support system design approaches [7]. [PERSON] emphasized the importance of continuously evaluating and adjusting support selection in burst-prone areas based on four crucial functions of a viable support system [187]. [PERSON] evaluated various rockburst support systems for their economic usefulness in deep tunnels and mines, providing guidelines for support system selection [188].
