Abstract On the basis of the spatial and temporal distribution, waveform characteristics and results of focal mechanism solution of the microearthquake swarms in Luoquanhuang area of Zigui county, the cause of the earthquakes are analyzed. The event is ore earthquake of rock burst type related to coal mine exploitation and mining activity, the microearthquake swarms belong to occasional local stress releasing.
Key words ：
Luoquanhuang
ore earthquake
mining activity
focal mechanism solution
stress releasing
