Research on Prospecting Prediction Based on Evidence Weight

There are many small and medium-sized orogenic copper deposits in the Jinman–Lanping area of Yunnan. In order to standardize mining, long-term planning, unified management, it is necessary further delineate prospecting areas. improve efficiency prospecting, a data-driven approach established. This paper uses weight evidence model make predictions, then delineates prospective area. The relevant layers geochemical anomalies remote sensing iron staining anomalies. Among them, anomaly layer mainly concentration-area (C-A) fractal separate background acquisition. iron-stained bands (1, 4, 5, 7), 3, 5) were combined for principal component analysis extract abnormal staining. Finally, using model, spatial element (evidence layers) from different sources combined, interaction between them was analyzed. It pointed out that has good prospects thus delineated.
