【摘要】 采用测井解译方法,对祁南煤矿72煤层煤体结构进行了分析,编制了煤层厚度等值线图,总结了构造煤的分布特征,对构造煤的成因进行了探讨,结果表明,构造煤厚度在走向和倾向上均呈厚薄相间分布,其形态与褶皱现象基本一致,其形成主要受区域构造应力所控制。更多还原

【Abstract】 By the interpreting logging methods,we analyzed the coal mass structure of No.72 coal seam in Qinan mine and plotted the isoline of coal seam thickness.We summarized the distributing characteristics of tectonic coal and discussed the genesis of tectonic coal.The results showed that the thickness of tectonic coal distributes alternatively thin and thick along the strike and the dipping direction and the geometries of tectonic coal are basically in accordance with folds’.Its formation is mainly controlled by the regional tectonic stress.更多还原
