【摘要】 通过运用瓦斯赋存构造逐级控制理论,研究了潞安矿区五阳矿井地质构造对瓦斯赋存的控制;结合五阳矿井大量瓦斯地质资料和实测数据,编制矿井瓦斯地质图;研究矿井瓦斯赋存规律,并对矿井进行瓦斯含量和瓦斯涌出量预测,评价煤层气(瓦斯)资源量,对煤与瓦斯突出区域进行预测。潞安矿区主体构造是NNE向、NE向展布的向、背斜褶皱及与EW方向构造的复合;矿井内天仓向斜的轴部地带瓦斯含量较高,小型断层和陷落柱比较发育,陷落柱密集分布于天仓向斜轴附近约800m的范围内。论文具体内容:编制五阳矿井瓦斯地质图;把煤层上覆基岩厚度、顶底板岩性、距断层的距离、煤层厚度、煤的挥发分5个相关因素进行多元分析,得出了多元分析瓦斯赋存情况与单因素煤层埋深情况相近,采用单因素煤层埋深进行瓦斯含量预测;依据五阳矿井的实际情况,把五阳矿井划分为15个块段进行资源量计算;依据实测参数和矿井主要地质构造特点,将井田内3#煤层埋深490m以深划为煤与瓦斯突出危险区。更多还原

【Abstract】 Through the use of gas deposit step by step structure control theory ,to study the Luan Mining, Wuyang mine geological structure of the gas distribution control; Combination of a lot of gas geological data and field data in Wuyang mine, making gas geological map; to study Mine Gas deposit law, and mine gas emission and gas content prediction, evaluation coal methane (gas) resource, coal and gas outburst forecast.Main structure of Luan mining area is NNE, NE anticline and compound structure of the EW direction; the gas content is high at axis of Tianchang syncline, relatively small-scale faults and collapse column development, collapse column is distributed axis of the Tianchang synclinal about 800m range. Paper details: Making Wuyang mine gas geological map; The depth of coal seam, roof and floor rock, the distance from the fault, coal seam thickness, volatile of coal, five related factors multielement analysis shows that the multivariate analysis of gas occurrence situation is similar to the case of single factor, coal seam depth of the single factor forecast gas content; Based on the actual situation in Wuyang mine, the mine was divided into 15 block, to calculate resources; based on the measured parameters and mine geological features to predict elevation +482 seam below, near axis of Tianchang syncline, coal and gas outburst is the most dangerous..更多还原
