The panel roadway in a coal mine in Shanxi province was in high stress state by the influence of stress concentration with dynamic pressure phenomena appearing, such as supporting difficulty, spalling, floor heaving, U-steel support pushed and threatened by burst. Microseismic monitoring technology was used for monitoring the roadway roof strata breaking. Two sets of sub-stations and 18 measuring points were installed to monitor and warning the burst disasters. Monitoring results showed that microseismic events occurred 0-4 times per day in the monitoring area with less energy. The microseismic events were concentrated in two areas, and were closely related to the extractive activities. More attention should be taken to these areas, monitoring of densely populated areas with microseismic events should be strengthened, and measures should be taken immediately to cope with abnormal events.
