Based on Acoustic Emission Technology for Monitoring the Instability State of Surrounding Rock During Metal Deposit Excavation
As a dynamic non-destructive testing method,acoustic emission technology can capture the acoustic emission signals of surrounding rock damage and fracture in the mining process of metal deposits in real time,which provides an important basis for evaluating the stability of surrounding rock.An Acoustic Emission-based Monitoring System(AE-MS)for the instability state of surrounding rock in metal deposit mining was studied.Key technologies such as Acoustic Emission signal preprocessing,sound source location,event feature extraction and pattern recognition were adopted.The real-time dynamic monitoring and early warning of the instability state of surrounding rock are realized.
