永陇矿区拜家河含煤区为一四周封闭的小型聚煤凹陷,本文通过区内的矿井多年生产中井巷揭露及以往地质勘探资料成果为依据,以煤田地质、构造地质、矿井地质和数学地质等理论为指导,分析含煤地层延安组成煤环境及其同沉积构造对煤层厚度的影响作用。
永隴礦區拜傢河含煤區為一四週封閉的小型聚煤凹陷,本文通過區內的礦井多年生產中井巷揭露及以往地質勘探資料成果為依據,以煤田地質、構造地質、礦井地質和數學地質等理論為指導,分析含煤地層延安組成煤環境及其同沉積構造對煤層厚度的影響作用。

Baijiahe coal-bearing zone of Yonglong mining area is small-scale enclosed coal-accumulating sag.Based on the production practice for many years and the geological exploration data in the past, using the theories of coal field geology, tectonic geology, mine geology and mathematical geology, the effect of coal-forming environment and sedimentary structure of Yan'an Formation to coal seam thickness was analyzed.
