A Tailings Dam Closed Library Governance Mathematical Model And Analysis In Tongling

At present,our country remained a lot bankruptcy mine of last century and its tailings dams.And at the same time,under the impact of capital for profit in market economy,they always ignored the management and maintenance of tailings dams.In recent years most scholars study of tailings dam has focused on the management impact of the tailings dam surrounding environmental,tailings dam's backfilling metal composition analysis and the analysis of few aspects in stability to the tailing dam.Most of these studies alleviate the pollution of surrounding environment in tallings dam,and to strengthen the improvement of the backfilling of dam safety at the same time.This paper focuses on the mathematical model analysis of having prevention system and backfilling materials production in tallings dam closed library project,summarized as follows:(1)Based on the mathematical model of the Manning formula and the method of "84",After respectively for intercepting flood ditch water discharge,library foreign exchange water modeling and through the model to calculate the specific data,set up a contrast model to examine the effects of the reconstruction project.In having prevention system transform of a tallings dam.In the reconstruction project of drain well,frist,we drain well charge before e amount of modeling analysis after transformation front row wells drainage ability of detailed data and establish a comparison model,second,analysis the transformation of the drain well drainage capacity changes before and after.At the same time,base on the formula of Gao Qielin,established a new model for flood regulating calculation with a special areas geology characteristics of the influence factors to the data.Detailed analysis of the backfilling materials under various conditions after rectification of the dam flood control ability.Effect the inspection of having prevention system transform through building a new mathematical model and analysis it.(2)Set up a planning model to analyzed and discussed the production of backfilling dam,build up a goal programming mathematical model with discount rate tR and analysis the value oftR,after all we can set up a mathematical model based on the weighted average method also called Capital Asset Pricing Model(CAPM),and analysis the project risks and characteristics showed in value of?.Secondly,determinethe constraints for mathematical model after cleared the sand mining engineering process,then established and analyzed the mining engineering combination of linear programming model.After analysis the result of mathematical model in this chapter,we can have a reasonable plan of backfilling materials production and mining,which have a maximal profit.
