| 摘 要： | 织金煤矿肥田二号井田位于黔西弧形构造体系之东翼，根据井田综合勘探地质成果分析，井田构造属华夏系构造体系，井田内褶曲轴和断层走向具有NE和NNE向发育特征，正断层主要分布于浅部和深部、逆断层主要分布于中深部。通过研究井田内褶曲轴和断层的生成机理，认为区内构造形迹属顺序生成和依次诱导派生，具有成生联系。初次应力作用形成主褶曲（珠藏向斜）、二次应力作用形成走向主断裂（F21、F42、F68）和次级褶曲（普戛小背、向斜）、第三次应力作用形成倾向断裂。井田地质构造研究为矿井设计、建设和生产提供了可靠的地质资料。

| Abstract: | The Feitian No.2 minefield, Zhijin coalmine is situated at the east wing of western Guizhou areuate structural system. According to minefield integrated exploration geological results analysis, the minefield belongs to Cathaysian structural system. Fold axes and fault strikes in the minefield all have NE and NNE directional development characteristics, normal faults are mainly distributed in shallow part and deep part, while reversed faults in mid-deep part. From researches on the genetic mechanism of fold axes and faults in the minefield, considered that structural features in the area are orderly formed and successively induced, provided with formative relations. The primary stress action formed the main fold （Zhuzang syncline）, the secondary stress action formed strike main faults 0721, 1742 and F68） and secondary folds （Puga small anticline and syncline）, and the third stress action formed dip faults. The research has provided with reliable geological data to mine design, construction and production. |
