摘　　要：为了对大兴矿未采掘区域的瓦斯地质条件做出预测评价,统计分析了大兴矿9次煤与瓦斯突出现象,从地质角度分析了突出与地质构造的关系及分布规律,分析发现:煤与瓦斯突出多发生在地质构造变化带、岩浆侵入区及其附近区域;还分析了在这些区域容易发生突出的原因,为采取有针对性的防范措施提供了依据。In order to predict and assess the gas geological conditions in the un-mined area of Daxing Mine, the paper statistically analyzed nine phenomenons of coal and gas outbursts occurred in Daxing Mine. From the geological point, the paper analyzed the relationship and distribution law of the outburst and geological structure. The analysis results showed that the coal and gas outburst often occurred in the geological structure exchanged zone, magma intrusive area and the adjacent area. The paper also analyzed the causes of outburst occurred in those areas, so as to predominate the basis to make the related preventive measures.
