Abstract The real-time monitoring and analysis of the microseismic activities of the cave rocks of a large underground water-sealed oil storage cavern in Jinzhou during the disturbance caused by strong excavation were performed using the Canadian ESG monitoring system. The potential failure regions of the cave rocks within the scope of monitoring were identified. The initiation，development and agglomeration process of the rock micro-cracks during excavation were reproduced. The P wave velocity was determined to be 5 200 m/s with the error of source location less than 8 m within the scope of the sensor array. Micro-cracks of rocks within the scope were aggregated into two bands. One was located to the east of water curtain tunnel 6，in between the water curtain tunnels 1 and 2，and had a low angle with the horizontal plane. The other was located in 2+40-2+60 mileage between the oil storage grotto 1-North and 1-South，and shared the same distribution with the diabase dikes in the region. The microseismic monitoring system identified the condition of the weak structural surface like dikes. The strong excavation disturbance of the large section oil storage caverns and the release of large amount of energy led to the“over damage”of rock and resulted in a large number of micro-cracks. The research results proved the feasibility of applying the microseismic monitoring technology in the special rock mass structures like underground water-sealed oil storage caverns.
