构造控煤在采矿安全中扮演着重要的角色，但现有资料对准东煤田构造研究较少，为使煤炭安全高效开采，需有针对性地进行煤田开采地质条件研究。以准东煤田构造特征为研究对象，通过统计断裂构造信息，使用分形维数(分维)定量表征了构造复杂程度，探讨了准东煤田现今构造特征和构造动力成因，分析了构造特征对煤田开采地质条件的影响。结果表明：准东煤田断裂以正断层发育为主，少量大型走滑断层；通过对构造复杂程度的定量表征，煤田大部分区域构造分维为0.5~0.9，表明煤田的总体构造格局较复杂。准东地区主要经历了晚海西期、印支期、燕山期及喜马拉雅期四期构造运动，其中在侏罗系煤层形成后，燕山期南北和东北向挤压应力对煤田改造作用较大，且在该期构造运动后准东煤田构造格局基本形成。受多期构造演化作用的控制，准东煤田形成了多种典型控煤构造样式：复向斜型褶皱构造划分了卡拉美丽山前凹陷带的构造格局；叠瓦式逆冲构造主要表现为构造上盘剥蚀严重，含煤性较差，而下盘煤系保存较好，两侧逆冲断层使得煤层遭受切割，煤层在断层的分界处工程地质条件较为复杂，增大了开采难度；推覆式构造主要表现为使煤系在垂向上重复出现，在煤田勘探时增加了找煤难度，发育部位普遍地应力较大，挤压构造应力的集中，在煤矿生产时易出现矿井动力灾害。因此，针对不同构造样式的煤层，需提出相应的开采模式。

The coal controlling of structures is critical to mining safety. However, few studies have been conducted on the structures of the Zhundong coalfield according to existing data. To ensure safe and efficient coal mining, it is necessary to conduct a study targeting the geological conditions for the coal mining of the coalfield. This study investigated the structural characteristics of the Zhundong coalfield. Based on the statistics of the fault structures, this study quantitatively characterized the structural complexity of the coalfield using fractal dimension, explored the current structural characteristics and tectonic dynamic genesis of the structures in Zhundong coalfield, and analyzed the influences of the structural characteristics on the geological conditions for coal mining. The results show that the faults in the Zhundong coalfield are dominated by normal faults and include a few large-scale strike-slip faults. As shown by the quantitative characterization of the structural complexity, the regional structures in the coalfield mostly have a fractal dimension of 0.5‒0.9, indicating that the Zhundong coalfield has a complex tectonic framework. The eastern Junggar Basin primarily underwent the Late Hercynian, Indosinian, Yanshanian, and Himalayan tectonic movements. After the formation of Jurassic coal seams, the north-south and northeast compressive stresses during the Yanshanian significantly transformed the coalfield. Moreover, the tectonic framework of the Zhundong coalfield was roughly formed after the Yanshanian tectonic movement. Controlled by multistage tectonic evolution, multiple typical coal-controlling structures have been formed in the Zhundong coalfield. Specifically, the synclinorium folded structures determine the tectonic framework of the Kalameili piedmont depression zone. For the coal-controlling imbricate thrust structures, their hanging walls are severely denuded and have poor coal-bearing properties, the coal measures on the foot wall are well preserved, and the coal seams are cut by the thrust faults on both sides. Moreover, the coal seams of the imbricate thrust structures have complex engineering geological conditions at fault boundaries, which increase the mining difficulty. The nappe structures cause the vertical recurrence of coal measures, increasing the difficulties with coal prospecting in the exploration of the coalfield. The nappe structures generally develop in parts with high in-situ stress, and the concentration of tectonic compression stress is prone to cause dynamic disasters in mines during coal mining. Therefore, it is necessary to develop corresponding mining modes for coal seams with different structural styles.
