Abstract: In order to help improve the supervision system of natural resources, fulfill the requirements of ecological civilization construction, and provide high-quality and efficient land use guarantee services, the investigation and monitoring of coal mining subsidence area is of great significance. Based on multi-source remote sensing data, combining traditional measurement technology and modern remote sensing technology, this paper constructs the investigation and monitoring system of coal mining subsidence area in Shanxi province. The results show that the distribution of coal mining subsidence area in Shanxi province is basically found out, and its total area is 6500km2, which is highly overlapped with the distribution of mining area and mined-out area in Shanxi province; and the land use is mainly forest land, cultivated land and grassland; and most of the land damage is light or moderate. 1221 villages which are affected by coal mining subsidence will be relocated, but more than 400 villages are not relocated.

Key words: mining subsidence area, investigation and monitoring, InSAR technology, land use, land destruction
