<p>The identification and mitigation of rockburst risks in multi-seam mining under complex conditions present a significant challenge. This study analyzes rockburst occurrences in working faces under complex conditions, establishing a refined model to describe the evolution of static and dynamic stresses. Hazardous rockburst areas were identified, and rockburst prevention measures were optimized. Rockbursts are typically accompanied by high-energy microseismic events, where microseismic velocity and dynamic stress exhibit exponential attenuation with increasing propagation distance of microseismic waves; higher energy levels correspond to faster attenuation rates. Numerical simulation results indicate that coal pillars and areas ahead of the working face are regions of static stress concentration, with microseismic events mainly distributed in high-stress zones and goaf regions, aligning well with observed microseismic events in the field. Upon reaching the working face level, dynamic stresses show localized points and clusters of stress concentration. The combined static and dynamic stress zones were classified into four hazard levels: none, weak, moderate, and strong. An abrasive jet axial cutting in the roof was implemented on-site to relieve stress and mitigate rockburst risks, and the key parameters were determined according to the divided rockburst dangerous areas. Field monitoring results show that microseismic energy is primarily released as high-frequency, low-energy events; the average periodic loading interval of the working face was reduced by 40.6%, and the roadway surrounding rock remains stable. These stress relief measures significantly reduced the rockburst risk. The findings provide a valuable reference for identifying and controlling rockburst hazards under multi-seam mining conditions.</p>
