Abstract：Unclear understanding of gas occurrence rule is a fundamental cause of frequent gas outburst disaster. Basing on gas occurrence tectonic control theory step by step, and combining with the datum of Jilin Province gas-geology map, tectonic stepwise control rule and zoning division of gas occurrence have been discussed. The results show that multiphase magmatism has increased the coal metamorphism of Jilin Province.Gas content and emission quantity in most coal fields of Jilin Province are higher owing to coal metamorphism increasing, hydrocarbon productivity enhancing and the bad gas permeability of wall rock. The coalmine gas occurrence and distribution in Jilin Province were divided into four high and outburst gas zones and tow common gas zones, that is, Tonghua high and outburst gas zone, Jiaohe-Liaoyuan-Meihe high and outburst gas zone, Yingcheng-Changchun high and outburst gas zone, Wanhong high gas zone, Shulan gas zone and Changbaishan gas zone.
