针对东庞矿北井9207工作面多断层地质构造和复杂水文地质条件，采用微震监测技术实时进行水害监测。通过对9207工作面整个监测周期的研究，确定未发现隐伏导含水构造水文地质异常，工作面范围内未发现底板垂向导水通道，实现安全回采。

 In view of the multiple faults geological structure and complex hydrogeological conditions of No.9207 Face in the north shaft of Dongpang Mine, the microseism monitoring technology was used to monitor the water disaster in real time. Through the study of the whole monitoring period of No.9207 Face, it was determined that no hydrogeological abnormal of hidden water conducting structure was found, and no vertical water conducting channel of floor was found in the range of working face. And the safety mining was realized.
