摘　　要：瓦斯突出区域划分是开展矿井瓦斯治理的基础。以瓦斯地质理论为指导,通过对矿井瓦斯地质特征及瓦斯赋存规律的研究,认为矿井构造是影响煤层瓦斯含量的主要因素,埋深、煤层煤质及围岩是次要因素。采用单项指标法及瓦斯地质的方法,对矿井煤与瓦斯突出危险性进行区域预测,最终以瓦斯含量≥8 m3/t为临界值,将井田由浅到深划分为突出危险区和无突出危险区。Division of gas outburst area is the basis of mine gas control.Based on the theory of gas geology,through the research of geological features and gas deposit law,the paper proposed that mine structure is the main factors of gas content,depth,coal seam and surrounding rock are secondary factors.Using single index method and gas geology to forecast the outburst danger area of mine coal and gas.The research eventually determined to make gas content ≥ 8m3 / t for the critical value,and divided the mine field into highlight outburst region and no obvious danger zone from shallow to deep.
