| 摘 要： | 利用榆神矿区榆树湾井田及其邻区钻孔资料,采用趋势分析法研究了2-2煤层厚度及其底板高程变化特征,探讨了煤层赋存特征及其成因。结果表明：2-2煤层由南东向北西赋存高程降低,同时煤层厚度变小;2-2煤层厚度的局部性变化受到盆地微古地貌特征或聚煤期基底沉降幅度的控制：煤层底板次级凹陷部位煤层增厚,次级隆起部位为煤层的次级减薄区,说明古地貌低洼处或盆地基底沉降幅度较大的地区对聚煤有利;榆树湾井田和邻区相比是煤层赋存最好的区域。

| Abstract: | Using the drilling data in the Yushuwan minefield and its neighboring region in the Yushen mining area,and the trend analysis approach has been used to study the variation features of No.2-2 coal thickness and floor elevation,discussed coal seam occurrence features and genesis.The result has demonstrated that: the floor elevation of No.2-2 coal is lowering down from southeast to northwest;meanwhile the coal seam thickness is decreasing.The local variation of No.2-2 coal thickness is controlled by basin micr... |
