Earthquakes and rock bursts can be forecast by monitoring electromagnetic emissions (EME). The electromatic emissions phenomenon in the rock burst process was studied using the EAE 04 electromagnetic and acoustic emission system both in the laboratory and in situ. The results show that the EME occur during the deforming and failing of the loading rock and coal. The EME intensity is low before the coal burst failure but increases suddenly when burst failure occurs. The EME impulse increases with the brea...
