Application Research of Microseismic Monitoring Technology in Coal Mine Excavation Face

To address dynamic hazards such as coal and gas outbursts and rockbursts during deep mining, this study takes a certain Coal Mine as the research subject. A mine-wide microseismic monitoring network was established using the Polish SOS microseismic monitoring system. By collecting, transmitting, and processing microseismic data in real time, the spatiotemporal distribution characteristics of microseismic events were analyzed. A dynamic hazard early warning model was developed based on the microseismic data, and targeted prevention measures were formulated in combination with the warning model. The results show that: Real-time microseismic monitoring and early warning effectively detected and mitigated multiple potential dynamic hazards. The early warning model provided sufficient time for the implementation of preventive measures. And the targeted prevention measures significantly improved mine safety and production efficiency. Practical applications demonstrate that this research has high practical value and broad applicability.
