Analysis On Deformation Law Of Tailings Dam And Early Warning And Forecast

The tailings dam is the important establishment in the mine production,it is a artificial high debris flow source,and environmental pollution is one of the non coal mine major hazard during the production operation of tailings dam stability is of great practical significance for mine safety.With the rapid development of communication technology and computer technology,the online safety monitoring system has been more and more accepted and used.In this paper,through theoretical calculation,numerical calculations were performed by using FLAC3D analysis of physical parameters on the tailings dam simulation software in tailings Waitoushan Iron Mine Xiaoxigou as an example of numerical simulation and on-line monitoring data obtained the following results through dynamic analysis,static analysis and the displacement of the.In this paper,the development situation of tailings reservoir(dam)at home and abroad and the problems of safety production at home and abroad are introduced in this paper.After comparison,it is found that there are still some problems in the investigation and design of the tailings dam in China,and the construction is not reasonable and so on.For the pre-processing of FLAc3D,the model was established by other numerical simulation or monitoring software profile map.In this paper,we use the FLAC3D5.0 version of the monitoring system for modeling and pre-processing of the method and the application of the method and the advantages and disadvantages compared to the traditional methods.The seepage analysis of tailings dam is carried out,and the variation law of the groundwater seepage line of the tailings reservoir under normal water level and flood level is obtained.The static analysis of the tailings,respectively,in the analysis of the normal water level and flood force of tailings dam under the distribution of safety factor calculation of tailings dam under two kinds of situations,from the results we can conclude that the tailings dam is stable under the static conditions.The dynamic response of tailings reservoir was calculated,and the dynamic response under the condition of normal water level and flood level was calculated.It is concluded that the tailings dam is safe to operate in two cases.The working principle and content monitoring system of tailings were introduced and analyzed simply,through the monitoring data to analyze the risk and safety of tailing reservoirs.
