Mine Dynamic Monitoring and Integrated Management Based on RS and GIS
The development of mineral resources is accompanied by serious threats to the geological environment in China. In order to balance mining order, mine environmental protection and ecological restoration, this article examines a case study of Ningwu mining area and proposes an accurate method for mine dynamic monitoring in mining area based on remote sensing (RS), which is a series of technical processes with RS images selection, mine development situation and dynamic monitoring which includes areas change and types transfer. Findings indicate that the area of bauxite pit, bauxite and coal dump increased, the area of coal industrial square decreased, coal dump and industrial square mainly transferred into bauxite pit. The organization and storage model were discussed for results integrated management by spatial database engine (ArcSDE).The application of results retrieval was developed by GIS components. This method can be considered as an effective approach for a wide range of mine development monitoring in mining areas in China.
