The regional itriutions features and the past five yeas accidents characteristios were investigated about mine fire accidents in China. The curent stuation of coal combustion forecast and prediction technologies were discussed fom thee aspects ofidentication of spontaneous combustion tendencycdetermiation of spontaneous combustion perod and montoring o inial coalspontaneous combustion.The appication status and suitability of diferent mine fre prevention & extinguishing technologies were analyzed,such as fling leakage,pressure balance,routing.inert gasesihibio,tre-phase foam . igh expansion foam and polymer materias.Fiaythe authors put forward that the realization of integrated mie fire prevention & extinguising system should persistent in the foundatin theories research a he bas sR&dDof technologies and equipmerts as the key.the promotig of advanced technologies as target aining at improving the efe ctiveness adaptation and economy of coal mine fire prevention and extinguisning technogies.which could proide the references for coal seam combustion and mine fre prevention induced by extenal cause.
