| Abstract: | The distribution of the medium making up the geophysical field of outbursts was studied in this paper. The spatiotemporal distribution of the key layer (i.e. outburst coal mass or disturbed and gas logged coal mass) was discussed based on its formation mechanism and the relation to geological structure. And the position and width of the stress dike ahead the working face were determined according to the theory of rock mechanics and elastic plastic mechanics. The research results offered a physical foundation of predicting the disaster caused by coal and gas outbursts by means of the geophysical methods. |
