为了查明薛湖煤矿的瓦斯赋存规律,研究了薛湖煤矿的地质构造特征,分析了薛湖煤矿的瓦斯赋存规律的控制因素。结果表明:薛湖煤矿瓦斯含量北高南低,深部高、浅部低;薛湖煤矿的瓦斯赋存与断层构造、褶皱构造、岩浆岩活动等地质条件密切相关;贫煤区瓦斯赋存的主控因素为煤层埋深,无烟煤区瓦斯赋存的主控因素为煤层埋深和顶板20 m内泥岩厚度。

In order to study the gas occurrence law of Xuehu Mine, the geologic structure characteristic of Xuehu Mine was studied, and the influencing factors of g as occurrence law were analyzed. The results indicated that the gas content was high in the north and was low in the south, was high in the deep part and was low in th e shallow part. The gas occurrence of Xuehu Mine was closely related to the geological conditions, such as fault structure, fold structure, magmatic activity and so on. T he main controlling factors of gas occurrence in the lean coal area was the buried depth of coal seam, and the main controlling factors of gas occurrence in the anthraci te area was the buried depth of coal seam and roof mudstone thickness within 20 m.
