构建煤炭开发利用效率分析模型,是理清煤炭开发利用效率现状以及探寻提高煤炭开发利用效率措施的重要基础。本文在理清煤炭开发利用效率含义的基础上,确定了模型边界、清单分析方法、影响评价方法,构建了煤炭开发利用效率分析模型,利用模型以2010年数据为基础对煤炭开发利用效率现状进行了评价。评价结果表明:煤炭开发利用全过程煤炭资源利用效率为15.42%;产出1GJ产品全过程投入为13.46元;利用1GJ煤炭工业储量实现资源价值11.17元;产出1GJ产品全过程SO_2排放为0.91kg、CO_2排放为203.02kg。
Constructing an analysis model for the efficiency of coal development and utilization is an important basis for clarifying the current situation of coal exploitation and utilization efficiency and exploring measures to improve the efficiency of coal development and utilization. On the basis of clarifying the meaning of the efficiency of coal exploitation and utilization, this paper determined the model boundary, inventory analysis method and impact assessment method, built the analysis model of coal exploitation and utilization efficiency, and made use of the data of the model to make the current situation of coal exploitation and utilization efficiency The evaluation. The evaluation results show that the utilization efficiency of coal resources is 15.42% in the whole process of coal development and utilization; the input of 1GJ product is 13.46 yuan; the resource value of 1GJ coal industry is 11.17 yuan; SO2 emission of 1GJ product is 0.91kg , CO2 emissions of 203.02kg.
