Abstract-The prediction study on coal and gas outbursts is ca rried out by monitoring some indices which are sensitive to the initiation of co al and gas outbursts. The values and changing rules of the indices are the found ations of coal and gas outbursts prediction. But now, only the data of one key m onitoring station is used in the coal and gas outbursts prediction practice, and the other data are ignored. In order to overcome the human factor and make full use of the monitoring information, the technique of multi-sensor target tracki ng is proposed to deal with the microseismic information. With the results of mi croseismic events， the activities of geological structure，fracture-depth of r oof and floor， and the location of gas channel are obtained.These studies indic ate that it is considerably possible to predict the coal and gas outbursts using microseismic monitoring with its inherent ability to remotely monitor the progr essive failure caused by mining.
Key words-coal and gas outbursts; microseismic monitori ng; data fusion
