The effective monitoring system should be based on a flexible and efficient query mechanism. But at presentthe query mechanism of coal mine moni- toring system is only concerned on the value variety of single sensors. It cannot provide queries about various ob- jects or the same object during different period limiting the ability of the coal mine monitoring system. This paper proposed an event-driven query mechanism based on temporal operators. This new query mechanism will enhance the query ability and be a basic supporting technique for coal mine monitoring system. Key words: coal mine monitoring system; temporal operator; query mechanism [1]
