Relationship between EMR and dissipated energy of coal rock mass during cyclic loading process
Coal rock mass EMR energy Dissipated energy Hysteresis loop area Amplitude
2012/3/28
Dynamic collapses of deeply mined coal rocks are severe threats to miners. In order to predict the collapses more accurately using electromagnetic radiation (EMR), this paper researched the energy con...
