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.
