Abstract: In order to meet the needs of mine land reclamation program development and improve the level of mine land reclamation information technology, this paper focuses on solving land damage prediction, land reclamation suitability assessment, engineering calculation, and land reclamation maps production.The geographic information system, remote sensing and 3D data visualization technology are applied to achieve mining reclamation auxiliary information system.With ArcGIS Engine, Visual Studio 2008, ENVI/IDL, we combined geographic information system, remote sensing and mathematical model with spatial database technology to build a set of land reclamation ancillary information system with strong scientific and versatility performance and functions of land damage prediction, land reclamation evaluation, planning, supervision and inspection.Through constructing a mining reclamation auxiliary information system, the planning efficiency and scientificity are improved, thus providing reference for information technology of mine land reclamation.

Key words: Mining land reclamation, GIS, RS, ArcGIS Engine
