摘要: 以趋势面法为主要研究方法,对大冶铁矿控矿构造及深部矿体定位规律进行了研究。结果表明:①岩体与大理岩的接触带是控制工业矿体产出的最主要因素,尤其是接触面上向岩体一侧凹进的“凹兜”直接控制了矿体产出;②接触带附近的其他构造,如2组追踪张裂面、“X”共轭裂隙、2组断裂的复合叠加、翻卷背斜转折虚脱部位等,对矿体的产出也有重要的控制作用;③矿区尖林山12-21勘探线深部为找矿最有利位置,以此为依据,在尖林山深部新发现铁矿体1 500万t。

Abstract: Based on trend surface analysis, the ore-body controlling structure and ore-body location of Daye Fe deposit is studied.The results show that① the main ore-body controlling structure is the contact zone of ore-bodies and rocks, especially the concaves which located in the intrusion controlled ore-bodies directly; ②the other structure around the contact zone, such as two groups of trace extension fracture, "X" type conjugate fracture, two groups of overprinting fracture and collapse locations of the hinge end of anticlines are also important ore-body controlling structure, ③K12-K21 in Jianlinshan is the best location of mineralization prospecting, and according to this result, 1.5×107 t iron mine were found in deep Jianlinshan.
