摘　　要：为了准确掌握和成煤矿二1煤层的瓦斯赋存规律并进行有效的瓦斯防治,收集、整理了近几年来和成矿井的资料,结合其实际地质构造情况,分析地质构造、顶底板岩性、水文地质对和成矿井瓦斯赋存的影响,并采用线性回归方法分析煤层埋深和底板标高对矿井瓦斯赋存的影响。研究结果表明:和成煤矿的地质构造、顶底板岩性对其瓦斯赋存特征有比较明显的影响;底板标高是影响二1煤层瓦斯赋存的主控因素。To grasp gas occurrence law of Ⅱ 1 coal seam in Hecheng Coal Mine accurately and prevent gas problem effectively, infornla- tion of Hecheng Coal Mine was collected and organized combined with the actual geological tectonic situation, the influence of geolog- ical structure,roof and floor lithology and hydrogeology to mine gas occurrence was also analyzed in the paper. Linear regression method was used to analyze the effect of buried depth of coal seam floor and elevation to mine gas occurrence. Research results show that, the influence of the geological tectonic and roof and floor lithology to mine gas occurrence is obvious in Hecheng Coal Mine, and the main control factor affecting gas occurrence of Ⅱ 1 coal seam is floor elevation.
