摘要
由趋势面分析证明 :在含煤地层形成时期 ,井田中部存在一条横贯东西的隆起带和一条近南北向的坳陷带横跨复合 ,这一格局控制了煤层厚度变化的总趋势 .随着中部隆起带逐渐南移 ,南北向坳陷向东部扩大 ,构建了不同煤层形成时期的复杂图像 .
During the formation of coal containing seams, an uplifted zone had been in the central part of the fields in Dayin. An nearly North_south direction depression zone was just cross the West_east direction uplifted zone. Thus, the general trend of coal thickness changes of the coal seam had been controlled by the above condition. During the formation of coal seam 2?1, the uplifted zone in the central part has gradully moved to the south. Therefore, the North_south direction depression has expanded to the East part.
