| 摘 要： | 对新集二矿推覆体下煤层构造规律进行了初步研究。认为推覆构造对煤层小构造起控制作用;煤层中小断层91%以上为正断层;层滑构造主要分布在11、8、6号煤的浅部,层滑构造是造成煤层厚度变化的主要因素;煤层变薄带呈SEE～NWW方向展布,与主构造线一致;落差3.5m以上断层影响综采工作面布置。

| Abstract: | Preliminary research on structural law of coal bed beneath nappe in No.2 mine of Xinji has been carried out, and hold that small structure of coal bed was controlled by the nappe structure, and 91% of mid- small faults in coal bed are normal faults; the slip sheet structure distributed mainly in the shallows of No.11? No.8? No.6 coal beds, and it's main factors caused change of coal bed thickness; the thinning zone of coal bed distributed along SEE- NWW direction, showing no difference with main structural line; the faults which amplitude of fault more than 3.5m may be influenced arrangement of working face on fully- mechanized coal winning technology. |
