Research progress and outlook on theory of thermodynamic disaster of coal mine in China

In order to provide decision-making reference for the scientific development of thermodynamic disaster of coal mine,and to promote the theoretical research and prevention and control technology of mine thermodynamic disaster in China,the paper defines the concept and property,systematically summarizes and analyzes the characteristics,research status and progress of mine thermodynamic disasters.It points out the main problems existing in the theoretical study of mine thermodynamic disaster in China:①It is still unclear the coupling mechanism of co-existence hazards between various types of mine thermodynamic disasters;②Basic research on complex systems of disasters has not yet been carried out;③The theoretical basis of the disaster superposition effect has not been studied,and the prevention and control mechanism of that has not yet been established;④There is still no inhibition theory and technology for the mechanism of secondary disasters;⑤Disaster environment detection technology needs to be improved,and emergency rescue technology is immature when there are hidden dangers in secondary disasters;⑥There is still a lack of efficient and rapid economic methods and techniques for detecting hidden disasters;⑦There is no integrated prevention and control system for mine thermodynamic disasters.And the development direction of the theory research on mine thermodynamic disaster is discussed and pros-pected.This paper puts forward the key field of theory research on mine thermodynamic disaster in China:①Basic theory of disaster complex system;②Coupling disaster mechanism between various types of disasters;③ Induction mechanism of the superposition and secondary effect of disasters;④Accurate detection theory and technology of hidden factors of disasters;⑤Emergency rescue technology during the disaster;⑥“Safety-Green-Efficient” integrated prevention and control technology system for mine thermodynamic disasters.
