七角井铁矿体空间赋存形态在浅部发生变化，为合理布置采矿工程，进行了浅部矿体空间形态及成矿原因分析。结果表明，铁矿床属沉积-变质型，古沉积盆地边缘曲线的差异性造成矿体的厚薄及延出、缩进等现象。罗雅楚山背斜轴部的南北矿体属同一成矿时期形成的同一层矿体，经后期地质构造运动发生层间错动断裂。断裂带自东向西倾覆，被错断后深部矿体抬起成为北矿体，浅部矿体下滑成为南矿体，断裂带内局部区域存有滞留的独立矿体。

Spatial form of Qijiaojing iron mine changed in shallow areas, spatial form and minerogenetic roles were analyzed to benefit underground mining designs. Results showed that the iron mine was a sedimentation-metamorphic typed deposit, and irregular lines of sedimentary basins leaded to variations of deposit thickness, extension or retraction. The north and south deposits on the anticlinal axis of Luoyachu Mountain formed as one deposit in one mineralization period, and deposit was separated due to lateral geological conformation movements. Afterwards, the fault zone tumbled from east to west, when the deep part lifted as a north deposit, and the shallow part fallen as a south deposit. Moreover, some independent deposits stayed in the fault zone as retentions.
