Abstract: Using different middle tunnel comparison method,to comparative study the different elevation of middle in the deep of Lanniping mining area,Dongchuan,expatiate the morphological characteristics of the Lanniping iron-copper orebody and ore-controlling factors.Studies suggest that Lanniping copper area of iron-copper orebody is mainly affected by the formation,structure（folds and faults) and magmatic rocks control,iron-copper ore bodies take the shape of lenticular,vein,layered distribution,orebody attitude is more stable,the orebody of thickness and grade change greatly.

Key words: Lanniping, Iron-copper, Ore-controlling factors
