<p>To address the frequent occurrence of high-energy events and elevated rockburst risk in structurally developed mines, this study investigates the WⅡ02040502 working face of Tunbao Coal Mine using high-precision microseismic monitoring data over the entire mining period. The spatiotemporal evolution and multi-parameter response characteristics of microseismic activity were systematically analyzed. A microseismic energy-frequency density cloud map was constructed to reveal clustering patterns in fault-dense zones and along the upper roadway. The coordinated anomalous responses of the b-value, A(b), P(b), and S indices before high-energy events were examined. In addition, the microseismic energy concentration zone was compared with the abutment pressure range derived from elastoplastic theory. Results show that microseismic activity exhibits a zonal clustering pattern jointly affected by fault development and mining-induced stress redistribution, with high-energy and high-frequency events concentrated in the upper roadway and fault-dense areas, consistent with the influence range of advanced abutment pressure. Before the occurrence of high-energy events, multiple parameters exhibited coordinated anomalous responses. Among them, an increase in the b-value, a decrease in A(b), and abnormal fluctuations in the S index may serve as potential combined warning characteristics under the specific geological and mining conditions of the studied working face. The microseismic energy concentration zone is mainly distributed 60–120&#xa0;m ahead of the working face, significantly exceeding the theoretical abutment pressure range (27.78&#xa0;m). This discrepancy reflects differences between idealized theoretical assumptions and actual geological conditions, as well as the extended effect of cumulative rock mass damage. These findings provide a scientific basis for identifying rockburst-prone zones, optimizing advanced support, and improving real-time hazard warning.</p>
