基于秭归罗圈荒微震群事件的时空分布、波形特征及震源机制解结果,分析了其成因.这次微震群属于冲击地压型矿震,与煤矿开采及回采工程活动有关,属于偶发的局部应力释放.
基于秭歸囉圈荒微震群事件的時空分佈、波形特徵及震源機製解結果,分析瞭其成因.這次微震群屬于遲擊地壓型礦震,與煤礦開採及迴採工程活動有關,屬于偶髮的跼部應力釋放.

On the basis of the spatial and temporal distribution, waveform characteristics and results of focal mechanism solution of the micro-earthquake 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 micro-earthquake swarms belong to occasional local stress releasing.
