| Abstract: |
| Microseismic monitoring technology is an important means for monitoring the law of overlying rock formation inbreak. In this paper, microseismic monitoring system is used to monitor and forecast about the roof collapse in the process of natural caving in the Pulang copper deposit. First, the network layout of the microseismic monitoring system is optimized, and the optimal monitoring system configuration scheme for the microseismic monitoring requirements of the first mining area is determined；By summarizing and analyzing the spatio-temporal evolution characteristics of microseismic activities, we delineated the fracture scope of rock mass under the influence of complex geological structure, and then identified precursory information and potential dangerous area of roof falling. |
