中文摘要：

本文简要分析了织纳煤田地质概况、煤田构造特征和煤层赋存情况，重点论述了构造分区及赋煤特征和控煤构造。根据含煤地层隆起幅度、煤层埋深相对大小，煤田构造划分为3个大区（拱褶区、拱凹区和凹褶区）8个小区（3个拱褶小区、3个拱凹小区和2个凹褶小区），各个构造分区赋煤特征各有差异，煤炭资源赋存以中西部三塘-关寨和百兴-岩脚2个拱凹小区保存较好，煤层埋深适中，易于勘查开发；煤田控煤构造包括褶皱控煤和断裂控煤两种，褶皱控煤构造以北东向斜歪隔档式褶皱为主，断裂控煤构造以区域大断裂为主，在区域性大断层附近断层较发育，属褶断型控煤，控煤构造样式有5大类11种类型，煤田内伸展构造样式和纵弯褶皱、断裂较发育。

英文摘要：

In this paper, the geological situation, coalfield structural character and coal occurrence condi- tion are introduced, the structural zonation, coal occurrence and coal controlling structure are summarized. According to the uplift degree of coat - bearing stratum and coal cover depth, the coal field are divided into 3 large zones and 8 small zones, the coal occurrence character of each zone is different, the coal occurrence of Santang - Guanzhai zone and Baixing - Yanjiao zone in middle and west area are kept fine, the cover depth is suitable and easy to explore. The coal controlling structure includes coal - controlling fold and coal - control- ling fracture, coal - controlling fold mainly is NE syncline partition fold, coal - controlling fracture mainly is regional fracture, the fault near the regional fracture is developed and belong to fanit -fold coal control. The coal - controlling style includes 5 broad classes and 11 narrow classes, extensional structural style, superposed fold and fracture are developed.
