Tailings Dam Online Safety Monitoring Technology And Study On It’s Early Warning Method

Tailings are a major hazard source.Due to the lack of in-depth analysis and Studyon the safety of tailings dam, lead to major accidents, not only caused huge economiclosses, but also brought about social and environmental impacts of bad. On the basisof project objective need of the development of tailings reservoir projects, according tothe safety analysis of tailings and the related issues of work, has made someachievements, the safety management of the tailings dam into the theoretical,systematic and scientific way, provide technical parameters are more reliable for thedesign and construction process of tail miners.The main research contents include:①Analysis of the existing security problems oftailings;②Research on safety monitoring technology of tailings Online;③Study onthe system of tailings security early warning method.The main research harvests are as follows:1.Introduction: tailings, Development of the tailings, The system of tailings areintroduced.2.Analysis of the existing security problems of tailings:Introduces China, LiaoningProvince, the existing security problems of tailings, causes the security issues,introduces the rules library security management of tailings, the research direction ofsafety management, and puts forward the Countermeasures of strengthening thesafety of tailings dam.3.Research on safety monitoring technology of tailings online: The tailing reservoirmonitoring technique are described, the tailings online monitoring system, theimplementation principle, safety monitoring index determination method areintroduced, the vibrating wire sensor accuracy of the online monitoring system toimprove the method of the platform construction of Liaoning Province, the heart ofmine tailings online monitoring is discussed, and according to the DandongQingchengzi the tailings are analyzed the tailings online monitoring examples.4.Study on the system of tailings security early warning method: In order to monitoronline Huatong mine tailings in Wafangdian City city as an example, using acombination of Geostudio and ANSYS, FLAC3D, through the Geostudio2007analysisand calculation, the tailing dam saturation line warning value, through ANSYS12.0and FLAC3D3.00analysis and calculation, determine the tailings all monitoring pointsearly warning value; and further gives the early warning indicators for qualitativeassessment the corresponding; establishes a fuzzy comprehensive evaluationmethod of tailing pond safety degree.5.Conclusion: The research work of this paper is summarized and prospected. This paper reports a total of54000words, including the development of tailings,tailings, system, analysis of existing safety problems of tailing, tailing research libraryonline safety monitoring technology, many aspects of the tailing pond safety problemsof tailing system security early warning method study, work systematically andcomprehensively; combined with a plurality of field of tailings the engineering exampleanalysis and verification, can provide reliable data and theory for tailings dam safetysupervision departments and relevant mining unit.
