二1煤是宜洛矿区主要可采煤层。阐述了宜洛矿区总体构造特征,分析了断层、向斜等地质因素对矿区二1煤层赋存和瓦斯分布的控制作用,探讨了区内不同时期、不同形式、不同规模的构造控煤因素对二1煤层开采技术条件的影响。
The second coal is the main coal mine in Yiluo Mining Area. The general tectonic characteristics of Yiluo mining area are expounded. The geological and tectonic factors such as fault and syncline are analyzed to control the occurrence and gas distribution of No.21 coal seam in the mining area. The effects of structural coal controlling factors at different periods, forms and scales on the coal mine are discussed Second, the influence of the technical conditions of coal seam mining.
