粉煤灰资源综合利用潜力评价方法及实例分析

Potential Evaluation Method and Instances of Integrated Utilization of Coal Ash Resources

本研究提出粉煤灰资源综合利用潜力评价方法,通过计算粉煤灰资源的产量、利润、净现值等主要经济技术指标,分析预测粉煤灰资源综合利用潜力。以典型粉煤灰资源为例进行实证分析,分析未来6年煤炭—粉煤灰—氧化铝、镓、氧化硅产业链间数量及经济效益间的动态关系,并对投资项目经济效益指标进行敏感性分析,为定量评价粉煤灰及其它矿产资源资源综合利用潜力提供应用范例。

In this study, a method is put forward of evaluating integrated utilization potential of coal ash resources. Through the calculation of production of coal ash resources, profits, net present value of the main economic and technical indicators,integrated utilization potential of coal ash resources has been analyzed and predicted. With a typical coal ash resource as an example for the empirical analysis, this paper analyzes the dynamic relationship between the quantity and the economic benefit of the industry chain of coal, coal ash, alumina, gallium, silicon oxide, and then analyzes the sensitivity of economic benefit indexes of the investment projects in six years. This will provide a paradigm and application example for quantitative evaluation of integrated utilization of coal ash and other mineral resources.
