## 8 Conclusions  
Taking multiple rockburst events in the vicinity of the 1300 longwall face in a certain mine as the engineering background, the evolution and distribution characteristics of the abutment pressure in the fully mechanized caving face were obtained through field microseismic and stress measurements, and the dynamic and static abutment pressure and their calculation models were proposed, the rockburst monitoring and early warning system of the fully mechanized caving face in the deep mine was constructed, and the corresponding anti-scour engineering optimization and active weak rockburst technology were proposed. In summary, the main research conclusions are as follows:  
1. By utilizing monitoring methods, including the vibration field and stress field, the scope of mining-induced effects on the fully mechanized 1300 working face in a certain mine was determined, the evolution and distribution characteristics of the surrounding rock abutment pressure of the 1300 working face were revealed, and the distribution range of the lateral abutment pressure in the goaf was initially obtained to be 120 m (the belt transport down chute of the 1301 working face). It was revealed that the essence of the rockburst problem in the adjacent area of the fully mechanized caving face was \"caused by the evolution superposition of the lateral support pressure of the 1300 stope and the original rock stress along the 1301 belt transport down chute\". 2. According to the theory of key strata, the load transfer characteristics of roof strata, and the theory of the limit equilibrium method, the calculation model of the dynamic and static abutment pressure of the longwall stope was established, and the quantitative calculation of the lateral abutment pressure of the stope was realized. It was concluded that 28 m-130 m of the 1300 goaf was the area affected by the abutment pressure, and a test of the model was realized through on-site stress detection. 3. The internal relationship between the push mining of the fully mechanized caving face and the rockburst in the adjacent area was analyzed, the microseismic frequency, spatial distribution characteristics and the relationship between the microseismic energy release and the push mining speed were analyzed, and the microseismic response law under different push mining speeds was revealed. Based on this, the optimization design of the push mining speed was carried out;
4. An integrated microseismic energy early warning index system for the actual mining face was established. Combined with the rockburst event on 8 July 2015, corresponding measures were proposed, including optimizing the mining speed and implementing controlled weak blasting in localized areas of the coal seam. These measures ensured the safe mining progress of the 1300 longwall face through the region and achieved secure extraction. The research outcomes of this project provide a theoretical foundation for preventing and controlling rockburst hazards, which holds significant importance for achieving safe and efficient mining in the mine.
