摘      要：Dynamic collapses of deeply mined coal rocks are *** order to explore new ideas for rock burst prevention,the relationship between entropy equations and dissipative structure was studied,and a concept-rock burst activity system(RAS) was proposed and its entropy was *** energy features of RAS were analyzed,and the relationship between electromagnetic radiation(EMR) intensity E and dissipated energy Ud was initially *** suggest that rock burst normally happens only when diS deS in RAS;RAS is the dissipative structure before collapse,and after which it become a new orderly structure,i.e.,a dead ,a statically orderly *** advanced that the effective way to prevent rock burst is to introduce entropy to the system for it keeps the system away from the dissipative structure.E and Ud of RAS are positively related,which is used as a bridge between dissipative structure theory and rock burst prevention engineering *** on this,and using the data of rock burst prevention for working face No.250205up of Yanbei coal mine,an engineering verification for the dissipative structure of RAS was carried out,which showed good results.
