Aiming at the increasingly serious pollution and ecological damage in mining cites, environmental information urgently are urgently needed to provide basis and decision-making for the economic transition of mining cites. This article describes main environmental problems existing in mining cites, as well as ways of monitoring these major environmental problems, such as the Landsat TM images are used in Land use dynamic monitoring, High Spectrum Images are used in the extracted vegetation monitoring, and the water quality change is monitored by the way of NOAA / AVHRR. Particularly, the effectual way of the Interferometric Synthetic Aperture Radar (InSAR) landslides monitoring is introduced, which is well applied to the opencast mine of Haizhou and Fushun in China with this technology. Differential interferometry using Synthetic Aperture Radar (SAR) is a powerful technology for detecting surface deformation of ground. Surface deformation can be analyzed from different phase of micro-wave between two observed data by SAR. The accuracy of measurement is less than plus-and-minus 1 cm. Achieved research results will provide early warning of environment disasters, rapid & real-time information and interpretation means for the mining cites.
