## 8 Conclusions  
This study proposes the \"overall-local\" coal burst prediction method and prevention strategies for isolated working faces, using the typical isolated working face of Wuyang Mine as the engineering background. The scientific novelty of this study lies in the development of an integrated prediction model that combines overall and local coal burst risks, providing a comprehensive framework for coal burst risk assessment. Key findings include:  
1. The spatial structure of the overlying strata and the abutment stress model were analyzed. A new bearing strength expression for coal in isolated working faces was derived, establishing the relationship between abutment stress and bearing strength. The \"overall-local\" coal burst prediction method and its associated mechanical criteria were identified, offering a novel approach to predict coal bursts in isolated mining areas. 2. Four distinct coal burst types were identified: (1) Both overall and local stability; (2) overall stability with local instability; (3) overall instability with local stability; (4) both overall and local instability. Based on these types, tailored prevention strategies were developed, including roof pre-splitting for overall control and coal pressure relief for local control. 3. The proposed prediction method was applied to the 76 working face at Wuyang Mine, where stability coefficients indicated overall stability (0.65 < I < 0.97) and local instability (1.05 < J < 1.55). The 10-meter-wide coal pillars ensured safe tunneling, demonstrating the practical application of the prediction model. 4. Drilling pressure relief was shown to effectively reduce local abutment stress, as confirmed by both numerical simulations and field measurements. This method significantly improved safety during excavation and enhanced the mine's technical and economic performance. Further testing is recommended to refine the method's application. 5. The layout of workings and other mining factors were found to significantly influence stress distribution and energy accumulation in isolated working faces. A well-designed layout can evenly distribute stress and reduce the risk of energy concentration, while poorly planned layouts, such as asymmetrical working faces, can lead to localized stress peaks and increase coal burst risks. Other factors, such as mining depth, goat width, and excavation rate, also contribute to energy accumulation. Deep mining increases stress levels, wide goafs alter stress transfer paths, and rapid excavation may cause sudden stress build-up, exacerbating risks. Optimizing layouts and mining parameters can effectively reduce stress peaks and mitigate coal burst hazards.

In future research, we plan to expand the current research framework, particularly in the following areas: Firstly, we will apply the existing theoretical model to isolated working faces in different geological conditions and mining areas to assess how coal burst risks vary under various mining environments. Secondly, further research will focus on developing and integrating more advanced monitoring technologies, such as real-time stress and deformation measurement systems, to improve early warning capabilities for coal burst risks. Lastly, by combining more field data with numerical simulation results, we aim to improve the accuracy and adaptability of coal burst prediction models, making them more effective in predicting and preventing coal burst accidents. Through these research directions, we hope to provide deeper insights into coal mine safety and coal burst prevention and contribute to the further development of this field.
