Therefore, the detailed study of the dam-break flow is important in the design and siting of tailing reservoirs, the disaster prevention and mitigation and the daily safe operation. In this paper, a mathematical model is proposed to describe the routing of the tailing flow in the downstream after tailing dam break based on the rheological properties of the tailing flow. The fourth order parabola is used for the discharged tailing flow process curve of the tailing reservoir dam-break, by which important parameters of the tailing dam break are determined such as the gross leakage of the tailing, the average width of the dam break, the maximum tailing flow at the tailing dam, the flow graph of tailings at the dam. Finally, with a tailing reservoir failure as an example, the mathematical model is used to study the dam-break tailing flow routing and the flow in the downstream in the context of the following three aspects: the plane area of the deposition, the longitudinal profile of the deposition and the cross section of the deposition., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=/gQri0OZCWlOT7UBX43N2A==, pdfFileSize=2615650, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
