Abstract: In order to realize multi-spectral data extraction of water body information in coal mining area, the Luxinling and surrounding coal mines in Pingxiang city are used as experimental areas. Under the inspiration of scholars at home and abroad on the use of water body index method to extract water information and application, the spectral characteristics of different objects in the experimental area are analyzed. Firstly, a mathematical normalization method is used to establish a synthesize water index model SWI ASTERxy on ASTER data. Then, the model is used to extract water information from the experimental area. Experiments show that the model can effectively extract the mining area. Water-like body, and the model can also be used in the extraction of different features in different regions by ASTER data (or other multi-spectral data). It has good effect and potential in remote sensing quantitative extraction, and has certain popularization value.

Key words: multi-spectral, extraction of water body information, water index, spetral characteristics, SWI ASTER
