| 摘 要： | 基于唐家河煤矿8#煤东翼瓦斯涌出量是西翼的5～10倍,分析了影响东、西翼瓦斯涌出规律的因素。经分析发现,构造、埋深、煤厚及变质程度均不是主导因素,也否定了东翼浅部发育的小松岩向斜的影响;通过进一步分析矿井东、西翼涌水量数据,发现唐家河煤矿瓦斯涌出量与涌水量存在互补关系,得出唐家河煤矿水文地质条件是影响该矿瓦斯涌出规律的重要因素。

| Abstract: | Based on the phenomenon that gas emission of east wing is 5~10 times as west wing in Tangjiahe coal mine,the factors of influencing the gas emission of east wing and west wing are analyzed,it found that conformation,buried depth,thickness and metamorphic degree of coal seam were not the dominant factors,and the influence of Xiaosongyan syncline in superficial part of east wing is denied too.But after analyzing water inflow data of east wing and west wing,complementary relationship between gas emission and water inflow is found.Hydrological geological conditions have a significant impact on gas emission laws in Tangjiahe coal mine. |
