摘　　要：为了研究韩城桑树坪井田3煤层的瓦斯赋存规律和主控因素,运用瓦斯地质学、构造地质学以及线性回归的方法,结合桑树坪井田地质勘探及现场实测瓦斯数据,分析总结了3煤层瓦斯赋存的规律。结果表明:桑树坪井田瓦斯含量北高南低,瓦斯压力受埋深控制明显,并得出煤层埋深、地质构造和顶板岩性是影响3煤层瓦斯赋存的主控因素。To study gas occurrence regularity in Ⅲ coal seam in Sangshuping Mine Field and the main influencing factors,using the theory of gas geology and linear regression method,combining with the data of mulberry ping gas coal geological exploration period and field testing,the rule of Ⅲ coal seam gas occurrence was analyzed. The results show that methane content in Sangshuping Mine Field is high in the north and low in the south,the gas pressure is controlled by depth,meanwhile,it is obtained that the coal seam buried depth,geological structure and roof lithology is the main controlling factors influencing gas occurrence of Ⅲ coal seam.
