Centre Line Damming Technology And Tailings Dam Seepage Stability Analysis

China is rich in mineral resources,about 90%of energy and raw materials come from mineral resources.With the continuous economic development,the demand for mineral resources was still growing trend.As it can be seen from the characteristics of minerals,ores or minerals main taste is generally low,and so the status quo will inevitably lead to continuous increase in output than in the tailings.Characteristics of tailings is the vast amount of small tailings,according to incomplete statistics,China's number four and so on tailings,five and so accounted for about 95%,meaning that the number of medium-sized tailings is less than 5%.Which without formal design and construction of the tailings also accounted for 36.19%,the proportion of disease resulting library,library high risk,security risk tailings have not ignored.This paper analyzes the current research tailings,through the large number of documents inspection and research,mainly on the process and its tailings dam seepage stability centerline method of analysis.Taking into account the current situation in the tailings project construction and operation during the existence of many uncertainties,as well as domestic law midline Damming Technology theoretical research and engineering practice inexperienced,this paper Liang ditch tailings project actual cases,Centre Line of tailings dam Construction process systematic study.This article from the tailings dam technology,combining with engineering design cases tailings,tailings dam construction process of midline law principles and its feasibility in the specific project analyzed;by engineering modeling,further different the method for calculating the tailings dam seepage and slope stability analysis,which analyzes the safety and reliability of the dam,tailings characteristics analysis method centerline dam,providing reliable calculation parameters for the design of subsequent tailings;Finally,on the midline method damming technology in engineering were discussed.Aiming at the possible construction and operation of process tailings pond midline engineering problems,seek solutions and accumulated experience in the construction and operation of future tailings.
