According to the study of the working face with a strong probability of rock burst, the EME can be used to forecast the rock burst and to check the effect of unloading blasting in coal mine.
The result of transient state analysis indicated the thermal-mechanical effect on seal face during loading, the seal surface parameter dropped steadily during unloading.
理想瞬态分析实例表明，加载过程中密封端面产生热机效应，稳定减载过程中端面参数平稳下降。
