With the development of deformation monitoring technology as well as the needs of the safety management of the mine tailings, has been developed for the integration of geometric engineering and localized deformation monitoring level, total station, GPS and other methods of measurement applied to the tailings dam external plane and periodic monitoring of the elevation deformation monitoring; rapidly Automatic Tracking Total Station (RTS), GPS, digital inclinometer (monitoring the tailings dams internal deformation), the saturation line measurement sensor, the water level measurement sensors and other cases together with computer technology, communication technology, database management technology, software development, research and development applications, to achieve a high precision real-time online monitoring of the tailings dam deformation monitoring of three-dimensional data, the reservoir water level, phreatic line hydrological data.Tailings dam deformation caused by many factors, in addition to the conventional deformation monitoring and analysis methods (curve polynomial fitting, multiple linear regression, Kalman filter) is applied to the tailings dam deformation monitoring analysis, this paper carried combines hydrology environmental and geological structure factors tailings dam the library shaped Monitoring and Analysis Research and Application; Therefore, this article carried a Kalman filter, multiple linear regression analysis, curve polynomial fitting analysis, combined with tectonic deformation analysis combined hydrological conditions deformation analysis time, load and geometric deformation multiple regression analysis, try to take advantage of the tailings starter dam settlement observations values and calculated theoretical total geological stratification legitimate settlement value calculated for the settlement of a tailings the experience coefficient; the same time, the establishment of a tailings pond dedicated database, Visual Studio2008development platform, the use of C++language features of object-oriented development tailings dam deformation monitoring and analysis query management system, by the CAD2010function is called to open the schematic layout of view of monitoring points monitoring points and the geological structure in conjunction with FIG. achieved Tailings management tailings deformation trends easily query, analysis, decision-making and efficient management of the effects.Finally, an example, draw some instructive conclusions, which makes the results of this research not only has a certain practical application significance and innovation.
