Application Research Of Mining-land-reclamation Information System Based On MapGIS

Land reclamation of mining area is produced by solving the damage caused by digging, collapse, occupation during the mining process. Its main purpose is tore cover land use value by taking remedial measures. The emphasis of land reclamation is the informational, digital, and scientific management of the data of land reclamation, however, the data of land reclamation of mining area has many characteristics, including wide range, large amount of data, complexity between data and so on. Traditional data management method is unable to meet the requirements of the development of contemporary land reclamation. Based on the analysis of the urgency of current land reclamation situation, this paper puts forward the research content and research methods combined with the analysis of the actual situation of Hongsong mine.Further more, with the help of powerful data processing and analysis function of the geographic information system this paper will establish a information system of land reclamation of mining area management based on Map GIS. Taken Map GIS software as a development platform, this system establishes information system of land reclamation of mining area, combined with redevelopment of secondary development software Map X provided by the Map GIS software, using Visual Basic 6 programming language as the development tool, and MATLAB as background data calculation and drawing tools. The function modules of this system include the data input module, editor module, data query module, land suitability evaluation module, mining subsidence prediction module, project output module and so on. They will be debugged verified by taking Hongsong mine as an example. The result shows that the system is debugged and achieves good operating results. The establishment of the system provides an effective platform for the workers of land reclamation of mining land and efficient management of mine.
