Abstract: In order to reseach the control laws of gas outburst in Hegang Coalfield, based on stepwise tectonic control theory of gas occurrence, with the analysis of the influence of tectonic evolution, fault and magmatic activity on gas outburst in Hegang Coalfield, gas outburst zone was divided. The results show that: Hegang Coalfield has experienced transformation of multi-period tectonic movement, strong fault cutting and magmatic activities and caused imbalance in the coalfield tectonic stress, the degree of metamorphism of coal and gas weathered zone, gas content and other factors; on the basis of this imbalance, the gas zone in Hegang Coalfield is divided into three high outburst gas zones and one low gas zone, namely Junde-Xing'an high outburst gas zone, Nanshan-Yixin high outburst gas zone, Xingshan high outburst gas zone and Fuli-Xinlu low gas zone.
