摘　　要：为了查明影响大平矿瓦斯涌出量的主控因素,在现场调研的基础上,系统收集和整理了大平矿二1煤层的瓦斯地质资料,分析了大平矿瓦斯涌出量影响因素,并用瓦斯地质数学模型进行筛选,得出影响瓦斯涌出量的3个主控因素为基岩厚度、煤层厚度和10 m泥岩影响系数(后者为顶板岩性组合特征)。并依据3个因素建模对未采区瓦斯涌出量进行了预测,为煤矿安全生产提供数据。In order to identify the main control factors of gas emission in Daping Coal Mine,this paper analyzes and calculates a great deal of data about Ⅱ1 coal seam gas geology which were collected from Daping Coal Mine,analyzes the impact factors of gas emission in Daping Coal Mine.Using gas geology mathematical model and screening three main control factors,such as the bedrock thickness,coal seam thickness and mudstone influence coefficient（10 m）.According to the three factors modeling and predicting the gas emission in non-mining area,provides a basis for safe production in Daping Coal Mine.
