| 摘 要： | 从东欢坨矿区域构造特征及构造演化出发，分析了区域地质构造对煤层赋存状况、矿井地质构造展布及构造类型等诸多方面的控制作用。研究表明，该区自石炭-二叠纪成煤后，经历了多期次不同方向的挤压，构造形迹主要形成于燕山期。燕山早期的北东向褶皱控制了区域性煤系的展布，矿井地质构造以断裂为主，主体展布方向为NE—SW向。根据矿区实际，认为应以研究区域地质构造及演化为着眼点，进行相应的地质预测预报工作。

| Abstract: | Dealing with the tectonics and tectonic evolution, the paper analyzed the regional geological control on coal seam occurrences, mine structural spreading and structural geometry characters in Donghuantuo mine, Kailuan mining area. The study area has experienced many stages of different directional compression since the coal-forming in Carboniferous-Permian. The structural features are mainly formed in the Yanshanian stage, the early Yanshanian NE-folds had controlled coal measures spreading. The fault is the main structure type in Donghuantuo mine, and the fault strikes are dominantly NE-SW. It is advised that the geological prediction should be based on tectonics evolution study and eoalmine reality. |
