红阳三矿深部采区处于张良堡背斜深部背斜轴两翼,构造展布受该背斜影响显著。通过补充勘探获得的钻孔岩芯和测井资料,研究发现深部采区内F60断层的发育状态与之前勘探资料有较大差异,该断层向西南并非延伸至深部采区边界,而是在13勘探线处尖灭,在13勘探线以南存在一条规模较小断层F60-1。断层发育情况直接控制了煤田煤系的赋存,F60断层的勘探新发现使深部采区12号煤层和1 3号煤层的可采面积有所增加。
The deep mining area of Hongyang No.3 Mine is located in the deep anticlinal axes of Zhang Liangbao anticline, and the tectonic distribution is significantly affected by this anticline. By supplementing the borehole cores and logging data obtained from the exploration, it is found that the development state of the F60 fault in the deep mining area is quite different from the previous exploration data. The fault does not extend to the southwest but extends to the deep mining area boundary The exploration line is pinch-out, and there is a smaller fault F60-1 south of the 13 exploration line. The fault development directly controls the occurrence of coal measures in coalfields. The newly discovered exploration of F60 fault increases the recoverable area of No.2 seam and No.13 seam in deep mining area.
