主　　题：electromagnetic radiation rock burst supporting resistance coal or rock 

摘      要：More accurate forecasting of rock burst might be possible from observations of electromagnetic radiation emitted in the *** analyzed experimental observations and field data from the Muchengjian coal mine to study the relationship between electromagnetic radiation signal intensity and stress during the fracturing of coal, or rock, and samples under *** results show that the signal intensity is positively correlated with *** addition, we investigated the change in the electromagnetic radiation intensity, the supporting resistance in a real coal mine environment, and the coal or rock stress in the mining *** data analysis indicates that:1) electromagnetic radiation intensity can accurately reflect the distribution of stress in the mining area;and, 2) there is a correlation between electromagnetic radiation intensity and supporting *** research has some practical guiding significance for rock burst forecasting and for the prevention of accidents in coal mines.
