摘　　要：煤矿瓦斯地质是煤矿最重要的生产地质条件之一。准确评价和预测煤矿瓦斯地质规律对于保障煤矿安全高效生产具有重要意义。在分析下石节煤矿地质构造背景的基础上,通过收集井田勘探与开采地质资料,系统总结了影响瓦斯涌出量的相关地质因素。分析认为:矿井瓦斯涌出量与断层褶皱等构造、煤层埋深、煤层底板标高和煤源有较为密切的联系,利用收集的瓦斯地质资料并选用逐步回归分析预测回采工作面绝对瓦斯涌出量,从而综合防治瓦斯灾害,保障矿区生产安全和矿工人身安全。Coal mine gas geology is one of the most important production geological conditions in coal mines. Accurate evaluation and prediction of coal mine gas geological law is of great significance for ensuring safe and efficient production of coal mines. On the basis of analyzing the geological structure background of Xiashijie Coal Mine, this paper systematically summarized the relevant geological factors affecting gas emission by collecting geological data of mine field exploration and mining. The analysis shows that the gas emission volume of the mine is closely related to the fault fold and other structures, the depth of the coal seam,the elevation of the coal seam floor and the coal source;the gas geological data collected and the stepwise regression analysis can be used to predict the absolute gas emission volume of the mining face, so as to comprehensively prevent and control gas disasters and ensure the safety of production and miners in mining areas.
