| 摘 要： | 通过福达煤矿井下钻屑解吸法实测8号煤层瓦斯含量,建立瓦斯含量预测方程,运用区域构造演化理论,对福达煤矿瓦斯地质影响因素进行了分析,总结了福达煤矿瓦斯赋存规律。研究表明:褶曲构造、煤层埋深、顶底板岩性、陷落柱和构造煤是影响福达煤矿煤层瓦斯赋存的重要因素;计算出矿井瓦斯梯度为0.0364 m3/(t.hm);8号煤层构造煤总体厚度达0.35 m,并沿煤层倾向呈增厚趋势,构造煤发育是该矿区瓦斯富集主控因素之一。

| Abstract: | With the gas content of No.8 seam Fuda Mine measured with the drilling cutting desorption method,a prediction equation of the gas content was established.The regional structure evolution theory was applied to analyze the gas geological influence factors in Fuda Mine and summarized the gas deposit law of Fuda Mine.The study results showed that the fold structure,seam depth,lithology of the seam roof and floor,sink hole and structure coal would be important factors affected to the seam deposit in Fuda Mine.Th... |
