Through the analysis of acoustoelectric indicators before the occurrence of the high-energy event and consulting relevant data, the following criteria for determining the risk of acoustic emissions and electromagnetic radiation can be determined: Electromagnetic radiation intensity or acoustic emission intensity has an obvious trend of continuous enhancement, namely “rising type”, the trend is close to the critical warning value, and the trend change rate exceeds the trend warning value, and the duration is greater than the minimum duration, η ≥ η C and T ≥ T C .
