Abstract Based on an analysis of the reflectance of burnt rocks in the Rujigou coalfield of Ningxia, this paper points out the key factors affecting the reflectance. With regression analysis, a simulation formula was established, which indicated the quantitative relationship between Fe 3+ and reflectivity at certain wavelengths. Then the author took the hyperspectral image of the coalfield as an example to find whether the formula is effective or not in calculating Fe3+ content of burned rocks. The result is satisfactory in that it coincides with the field investigation. It also proves the practicability of the hyperspectral remote sensing technique in mineral resource exploration.
