龙岩陈山矿区滑覆、推覆构造特征及其控煤作用分析
|
摘要
文章通过陈山矿区滑覆、推覆构造分析,发现滑覆、推覆构造有4种类型,即脱底滑覆断层、脱顶滑覆断层、层间滑覆构造和层间推覆构造;它们对可采煤层的控制具有一定的规律性:其一,沿张性断裂面发生重力滑动时,其后缘部位往往拉薄缺失,煤系受到较大破坏,中带煤系保存较好;其二,层间逆冲推覆构造,应寻找原地系统控煤、断层上下盘同时控煤,原地系统的控煤性要好于外地系统。应寻找倾向上的富煤带;进行此项研究为龙岩陈山矿区进一步寻找富煤带指明了方向。
Through the analysis of the nappe and nappe structure in the Chen Shan mining area,it was found that there are 4 types of nappe and nappe structure,that is,the sliding overlay fault,the top slip fault,the interlayer slip structure and the interlayer nappe structure,and they have certain regularity for the control of the recoverable coal seam: first,the gravity sliding along the tensional fracture surface.The back edge of the coal system is often lost,the coal system is greatly destroyed and the coal measures in the middle zone are well preserved; secondly,the interlayer thrust nappe structure should seek the coal control of the original system and the coal control at the same time,and the coal control of the original system is better than the other system.We should look for the tendency of the rich coal belt.This research had pointed out the direction for further searching for the coal rich zone in Longyan Chen Shan mining area.
