Characteristics of electromagnetic radiation signal of coal and rock under uniaxial compression and its field application

Rockburst is a serious threat to the safety and efficiency of coal-mine production in China. Accurate monitoring and prediction of rockburst is an ongoing challenge in coal mining. Electromagnetic radiation (EMR) technology is a real-time and non-contact prediction method for changes in the mechanical parameters of coal or rock. In this paper, uniaxial compression testing of coal and rock samples was carried out, EMR data were collected and...
