摘　　要：为了研究鹤岗煤田瓦斯突出构造控制规律,基于瓦斯地质构造逐级控制理论,通过对鹤岗煤田构造演化、断层以及岩浆活动对瓦斯突出的影响分析,对鹤岗煤田进行了瓦斯突出区带划分。研究结果表明:鹤岗煤田经历了多期构造运动的改造,强烈的断裂切割及岩浆活动造成了煤田内构造应力、煤的变质程度以及瓦斯风化带、瓦斯含量等因素的不均衡性;依据这种不均衡性将鹤岗煤田瓦斯分带划分为3个高突瓦斯区、1个低瓦斯区,分别为峻德-兴安高突瓦斯区、南山-益新高突瓦斯区、兴山高突瓦斯区、富力-新陆低瓦斯区。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.
