Study On Integrated Pre-control Technology For Land Reclamation In Open-pit Dump

According to the comprehensive technical problems in openl-pit mine mining and land reclamation,used the method of comprehensive analysis and Simulation,maked the combination of Open-pit mine mining process and soil reconstruction, to realize Open-pit stripping and mining and exhaust integrative method, optimization of dumping sequence and position.To collected the raw data of measurement and the heidaigou open-pit's topographic map of DWG format , and eliminating gross errors from the data, establishedthe mining stope and dump fine DEM model, quantitative Calculation of the mellow soil that cover on the dump surface, to determine the amount and the average thickness of soil for the region. forecast the Soil covering the region,Output Prediction and previewed the result.Then through analysis and researeh, to improve reclaim craft and plan of design on this basis,and offer the visual model of consulting;to design and revise reclamation administration seheme,survey materials are carried on to revise digital elevation model(DEM)of mining area,and to export DEM in various forms and execute corresponding calculations and analyses on the basis of DEM.So we can instruct land reclaim and environmental protection to be implemented effectively, and carrying out the dump digital management,in the Open-pit mine, this technique can transform the management mode to fine and concentration and digital mnagement.According to the local situation, puts forward the standards for land reclamation.
