# A Comprehensive Review of Mechanisms, Predictive Techniques, and Control Strategies of Rockburst
## 6 Rockburst Prevention and Control
### Rockburst Support Design Principles  
Strategy encompasses the overall management of underground construction operations, while tactics focus on the effective use of tools and problem-solving in the field. Many engineers tend to focus on tactics, as their day-to-day work demands quick solutions to pressing challenges. Strategic thinking, however, requires long-term planning and a proactive approach to mitigating rockburst damage. [PERSON] [127] distilled practical field experiences into clear, easy-to-understand principles for designing rockburst support, as outlined in Figure 16.  
The first principle is to minimize rockburst risk through methods such as changing the tunnel location, using alternative excavation methods, adjusting stope size and shape, modifying the mining sequence, or changing technologies. The second principle supports the use of yielding support in hazardous conditions, where the support must be flexible and able to withstand convergence without self-destruction while absorbing energy to ensure tunnel safety [2]. A yielding support system works with the surrounding rock mass, but the weakest link in conventional systems is often the connection between bolts and screens. Rock support design often overlooks the impact of the rock mass between bolts on the support system. To establish an effective system, holding components must be paired with reinforcing elements and surface support, forming an integrated approach. The fifth principle is simplicity; rock support should be easy to fabricate, install, and maintain to be accepted by mine operators and miners. Mining businesses must prioritize safety over cost savings, as rockbursts can lead to damage, equipment loss, decreased output, injuries,

and fatalities [2]. The final principle highlights the importance of adaptability to a wide range of ground conditions to prevent and control damage, reduce investment risk, and protect workers. Understanding these seven principles (Figure 16) improves rockburst mitigation. Rockbursts can occur as a result of a variety of circumstances, including geological conditions, stress levels, and mining operations. As a result, prevention and control strategies must be tailored to the unique rockburst type and mechanism at hand. Mining industries, for example, can install seismic monitoring systems and rock strengthening techniques, such as rock bolting, to prevent seismic rockbursts caused by unexpected energy release in the rock mass. Pre-excavation analyses and controlled blasting techniques can help to reduce dynamic rockbursts induced by excavation disturbances in the rock mass. Gravity-induced rockbursts can be avoided by reinforcing the rock mass and uniformly distributing the load with support systems such as rock bolting or shotcreting. Hybrid rockbursts, which are a combination of several kinds of rockburst, can be difficult to prevent and control; hence, mining companies can employ a combination of the approaches listed above, depending on the unique mechanism involved.
