【摘要】：摘要：矿产资源属不可再生资源,在矿产开发过程中尽可能的回收利用资源成为采矿的一个重要准则。进入快速发展的市场经济时代,世界各国均日益重视矿产资源经济的优化利用及管理工作,不断发展深化研究矿产资源配置及管理相关工作,矿产资源资产化逐渐开展,矿产资源有偿使用工作基本得以实现,矿产资源经营主体也逐渐向多元化转变。在矿产资源优化管理发展中一个关键问题就是在建设项目压覆矿产资源时,如何界定压覆矿产资源的价值,并在此基础上做好压覆矿产资源建设项目的经济评价。本文结合平果铝土矿压覆矿资源实际情况和特点的基础上,结合经济学基本原理及相关规范,建立相关经济评价指标,利用经济评价模型对矿山开发经济进行评价综合,利用多种目标优化方法,构建压覆矿山开发的经济评价模型,并对矿山开发生产环节中的各种利益指标进行最优区分评价。主要研究成果分为以下几个部分： (1)分析国内外铝土矿产资源特点,并预测分析国内铝土矿价格变化特征,分析压覆铝土矿开发过程的难点,选择采用时间序列B-J法预测经济评价参数—铝金属价格的预测,为经济评价的主要影响因素提供参考依据,确定压覆矿产资源评价系统的各主要因素,建立产品价格因素预测模型。 (2)建立动态的效益最大化平衡模型。首先分析各子系统主要成本因素(氧化铝生产成本、铝土矿成本、搬迁成本),确立各子系统独立核算的成本价值数学模型。然后以总系统效益最大化为目标,在往年氧化铝产品价格统计的基础上,利用时间序列预测方法预测氧化铝产品价格变化,建立总系统的单目标利益最优化评价数学模型。 (3)建立总系统单目标利益最优化数学模型,利用C语言编程。通过VC++6.0编程软件,以经济评价为模型,实现了压覆资源搬迁开采的经济评价软件。软件可实现变动参数的输入功能,也可作为独立的经济评价子模型,并与氧化铝产品市场价格预测相联系,实现压覆矿产资源经济评价的敏感性分析。 (4)利用敏感度分析方法,确定各子系统单目标效益最优化指标敏感度,利用敏感度分析结论,优化排列各子系统单目标权重,实现多目标优化决策的矿产资源经济评价。
[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.
