At present

the single sensor is often applied in the mine safety monitoring system to monitor the safety of underground working conditions in our country.In order to overcome that the single sensor is unable to accurately judge whether the danger is to occur

based on the fuzzy set theory

the kind of fusion monitoring method which uses multi-sensor fuzzy information fusion is proposed.The state messages obtained by multi-sensor are fuzzily processed

and integrated by this fusion method

so that the precise state estimation of equipments can be realized.This method has fully used the multiple messages which the sensor provides

enhanced the recognition rate of the system.The experimental result shows that the identification result of the multi-sensor information fusion is better than that of the single sensor.Thus

the multi-sensors fuzzy information fusion is the new method which has the potential.
