【摘要】：摘要：礦產(chǎn)資源屬不可再生資源,在礦產(chǎn)開發(fā)過程中盡可能的回收利用資源成為采礦的一個重要準(zhǔn)則。進入快速發(fā)展的市場經(jīng)濟時代,世界各國均日益重視礦產(chǎn)資源經(jīng)濟的優(yōu)化利用及管理工作,不斷發(fā)展深化研究礦產(chǎn)資源配置及管理相關(guān)工作,礦產(chǎn)資源資產(chǎn)化逐漸開展,礦產(chǎn)資源有償使用工作基本得以實現(xiàn),礦產(chǎn)資源經(jīng)營主體也逐漸向多元化轉(zhuǎn)變。在礦產(chǎn)資源優(yōu)化管理發(fā)展中一個關(guān)鍵問題就是在建設(shè)項目壓覆礦產(chǎn)資源時,如何界定壓覆礦產(chǎn)資源的價值,并在此基礎(chǔ)上做好壓覆礦產(chǎn)資源建設(shè)項目的經(jīng)濟評價。 本文結(jié)合平果鋁土礦壓覆礦資源實際情況和特點的基礎(chǔ)上,結(jié)合經(jīng)濟學(xué)基本原理及相關(guān)規(guī)范,建立相關(guān)經(jīng)濟評價指標(biāo),利用經(jīng)濟評價模型對礦山開發(fā)經(jīng)濟進行評價綜合,利用多種目標(biāo)優(yōu)化方法,構(gòu)建壓覆礦山開發(fā)的經(jīng)濟評價模型,并對礦山開發(fā)生產(chǎn)環(huán)節(jié)中的各種利益指標(biāo)進行最優(yōu)區(qū)分評價。主要研究成果分為以下幾個部分： (1)分析國內(nèi)外鋁土礦產(chǎn)資源特點,并預(yù)測分析國內(nèi)鋁土礦價格變化特征,分析壓覆鋁土礦開發(fā)過程的難點,選擇采用時間序列B-J法預(yù)測經(jīng)濟評價參數(shù)—鋁金屬價格的預(yù)測,為經(jīng)濟評價的主要影響因素提供參考依據(jù),確定壓覆礦產(chǎn)資源評價系統(tǒng)的各主要因素,建立產(chǎn)品價格因素預(yù)測模型。 (2)建立動態(tài)的效益最大化平衡模型。首先分析各子系統(tǒng)主要成本因素(氧化鋁生產(chǎn)成本、鋁土礦成本、搬遷成本),確立各子系統(tǒng)獨立核算的成本價值數(shù)學(xué)模型。然后以總系統(tǒng)效益最大化為目標(biāo),在往年氧化鋁產(chǎn)品價格統(tǒng)計的基礎(chǔ)上,利用時間序列預(yù)測方法預(yù)測氧化鋁產(chǎn)品價格變化,建立總系統(tǒng)的單目標(biāo)利益最優(yōu)化評價數(shù)學(xué)模型。 (3)建立總系統(tǒng)單目標(biāo)利益最優(yōu)化數(shù)學(xué)模型,利用C語言編程。通過VC++6.0編程軟件,以經(jīng)濟評價為模型,實現(xiàn)了壓覆資源搬遷開采的經(jīng)濟評價軟件。軟件可實現(xiàn)變動參數(shù)的輸入功能,也可作為獨立的經(jīng)濟評價子模型,并與氧化鋁產(chǎn)品市場價格預(yù)測相聯(lián)系,實現(xiàn)壓覆礦產(chǎn)資源經(jīng)濟評價的敏感性分析。 (4)利用敏感度分析方法,確定各子系統(tǒng)單目標(biāo)效益最優(yōu)化指標(biāo)敏感度,利用敏感度分析結(jié)論,優(yōu)化排列各子系統(tǒng)單目標(biāo)權(quán)重,實現(xiàn)多目標(biāo)優(yōu)化決策的礦產(chǎn)資源經(jīng)濟評價。
[Abstract]:Abstract: mineral resources are non-renewable resources, and recycling of mineral resources as much as possible has become an important criterion in mining. In the era of rapid development of market economy, countries all over the world pay more and more attention to the optimal utilization and management of mineral resources economy, and continue to develop and deepen the research on mineral resources allocation and management. The paid use of mineral resources has been basically realized, and the main body of mineral resources management has gradually changed to diversification. One of the key problems in the development of mineral resources optimization management is how to define the value of overlying mineral resources when the construction projects overlay mineral resources, and on this basis, to do a good job in the economic evaluation of the construction projects of overlying mineral resources. On the basis of the actual situation and characteristics of the cladding resources of Pingguo bauxite mine, combined with the basic principles of economics and relevant norms, the related economic evaluation indexes are established, and the economic evaluation model is used to evaluate the mining development economy synthetically. The economic evaluation model of overlying mine development is constructed by using various objective optimization methods, and the optimal differentiation and evaluation of various benefit indexes in mining development and production are carried out. The main research results are divided into the following parts: 1) analyzing the characteristics of bauxite mineral resources at home and abroad, predicting and analyzing the changing characteristics of domestic bauxite prices, analyzing the difficulties in the development process of bauxite overburden, and choosing the time series B-J method to predict the economic evaluation parameters-the prediction of aluminum metal prices. This paper provides a reference for the main influencing factors of economic evaluation, determines the main factors of the evaluation system of overlying mineral resources, and establishes the forecasting model of product price factors. A dynamic equilibrium model of maximum benefit is established. Firstly, the main cost factors of each subsystem (alumina production cost, bauxite cost, relocation cost) are analyzed, and the mathematical model of cost value of each subsystem is established. Then, aiming at maximizing the total system benefit, on the basis of previous alumina product price statistics, the time series prediction method is used to predict the alumina product price change, and the mathematical model of single-objective benefit optimization evaluation of the total system is established. The mathematical model of single objective benefit optimization of the total system is established, and the C language is used to program it. By using VC 6.0 programming software and taking economic evaluation as the model, the economic evaluation software of overburden resources removal and mining is realized. The software can be used as the input function of variable parameters and as an independent sub-model of economic evaluation, and can be associated with the prediction of market price of alumina products, and the sensitivity analysis of economic evaluation of overlying mineral resources can be realized. (4) the sensitivity analysis method is used to determine the sensitivity of each subsystem's single objective benefit optimization index, and the result of sensitivity analysis is used to optimize the weight of each subsystem's single objective, so as to realize the economic evaluation of mineral resources for multi-objective optimization decision.
