求翻译：由于泥炭沼泽发育的古地形起伏不平，使泥炭层的堆积存在一个“填平补齐”的过程，因此煤层厚度随着基底地形的高低而有所变化，该种成因的煤厚变化一般影响规模较大。煤层的产状发生明显的变化．煤层的下部出现藉节状和倒丘状等现象．煤层底板凹凸不平而顶板正常平整。是什么意思？

Peat swamp development of the ancient terrain is hilly, so that the accumulation of the peat layer there are a "Tianpingbuqi the process of seam thickness vary with the level of the base terrain, the size of the general impact of the causes of coal thickness change larger. The occurrence of coal sea

Because the moss land growth ancient landform fluctuation is uneven, causes the peat coal level the stack to have “makes up” the process, therefore coal bed thickness has the change along with the basis terrain height, this kind of origin coal thick change general influence scale is big.The coal bed

Due to the undulating terrain of the peat development, enable the accumulation of peat layers for a "fill a gap", so coal seam thickness change as the basement level of terrain, the kind of causes of coal thickness change affecting the larger. Of coal seam occurrence of dramatic change. Appears in t
