Abstract: Mine gas occumence law and emission prediction are important theoretical basis for mine gascontrol. 'This paper deeply studies and analyzes the oontrol factors of gas geological occurrence law in Jin-fa coal mine. 'The control factors such as geological strnucure ，overlying bedrock thickness，roof and floorlithology and hydro geological conditions d Jinfa coal mine are qualitatively analyzed. It is determinedthat the buried depth is the key factor that affects C and C。 coal gas content.Combined with the meas-ured gas emission，the regional outburst risk of ooal and gas could be predicted.The results show thatthere is a positive correlation between coal seam depth and gas content.Gas pressure is the most impor-tant index to determine the risk of gas outburst in Ca and C。 coal seam ， the area with gas pressure greaterthan 0.74 MPa in the mine boumndary has outburst risk.'T'he outburst risk area of coal mine is maimly inthe northwest of the mine boundary near the 2 coordinate point of the mine.

Key words: gas 0ocuence law , gas emission prediction , coal and gas outburst prediction
