Based on statistical analysis of the gas-geology data and the gas content of 15th coal seam in Liangshun Mine, the author found the Seam gas existence characteristic in this mine to be studied by using gas-geology research methods. On the basis of gas-geology rules in Liangshun Mine, the author found several main gas-geology factors which have effect on seam gas existence of 15th coal seam, such as geologic structure, seam burial depth, coal seam roof and floor lithology. The main control factor of gas existence has been demonstrated to be seam burial depth and geologic structure only impacts gas existence locally.% 在良顺煤矿瓦斯地质资料统计，以及15号煤层瓦斯含量测定成果的基础上，运用瓦斯地质学的研究方法总结了该煤矿15号煤层瓦斯赋存特征。在矿井瓦斯地质规律的基础上，分析得出了影响矿井15号煤层瓦斯赋存的主要地质因素：地质构造、煤层埋藏深度、煤层顶、底板岩性的关系，认为煤层埋深是影响瓦斯赋存的主要控制因素，地质构造只在局部影响煤层瓦斯赋存。
