《国民经济和社会发展第十二个五年规划纲要》提出：“十二五”期末单位国内生产总值能源消耗比“十一五”期末下降16%左右，这是“十二五”规划目标中最重要的约束性指标之一，充分体现了落实科学发展观，加快经济增长方式转变，建设资源节约型、环境友好型和实现可持续发展的要求，同时也体现了我国政府面对世界能源、环境压力日益增加的责任与承诺。 目前，中国铁矿资源中易选的铁矿资源日益减少，铁矿资源特点是贫矿多，富矿少，伴生矿产多，铁矿石组分比较复杂，矿石嵌布粒度大多较细，给选矿造成一定的困难。从技术上讲，冶山铁矿的技术和设备相对比较落后，设备工艺效率低；从管理上讲，由于一味追求经济效益，冶山铁矿的能源管理基础是比较薄弱的，另外矿山行业目前尚无完整的节能分析评价体系，导致在冶山铁矿强化能源管理任务非常艰巨，建立适合冶山铁矿生产工艺特点的节能分析评价体系，研究其重点节能措施十分重要。 本文通过冶山铁矿具有代表性的采矿、选矿耗能案例，建立采矿、选矿工艺流程图，制定能源流向表、能源平衡表、能源结构分配饼型图,，建立了冶山铁矿较完整的能源计量统计体系与分析图表，采用万元工业产值能耗、单位产品能耗计算法，对冶山铁矿能耗指标水平进行分析评价，为能效考核与节能潜力的分析，提供了理论和应用依据。从不同角度评价冶山铁矿能源结构、能源流向比率，判定能耗变化趋势和问题，为能源管理和节能评价分析提出解决方案，通过方案的实施，对提升冶山铁矿能源管理水平，提高各种能源利用效率具有很好效果。 关键词：铁矿；节能；分析；评价；体系；研究 |

“Outline of the Twelfth Five-Year Plan for Economic and Social Development “" states that the energy consumption per unit of gross domestic product (GDP) at the end of the 12th Five-Year Plan is about 16% lower than that at the end of the 11th Five-Year Plan. This is one of the most important binding targets in the 12th Five-Year Plan. It fully embodies the requirements of implementing the scientific concept of development, accelerating the transformation of economic growth mode, building a resource-saving and environment-friendly and sustainable development. But also reflects the Chinese government to face the world's energy, environmental pressure increasing responsibility and commitment. At present, China's iron ore resources in the increasingly easy to reduce the iron ore resources, iron ore resources are characterized by lean ore, less ore, associated minerals, iron ore composition is more complex, ore embedded grain size is mostly fine, for the beneficiation have some difficulties. Technically speaking, the metallurgical iron ore technology and equipment is relatively backward, the equipment process efficiency is low; from the management point of view, due to the blind pursuit of economic benefits, Yanshan Iron Mine's energy management base is relatively weak, while the mine industry is currently There is no complete energy-saving analysis and evaluation system, which leads to the difficult task of strengthening energy management in Yanshan Iron Mine, and it is very important to establish energy-saving analysis and evaluation system which is suitable for the production process of smelting iron ore. Based on the representative mining and mineral energy consumption cases in Yanshan Iron Mine, this paper establishes the mining flow chart of mining and mineral processing, formulates energy flow table, energy balance table and energy structure distribution pie chart. Established a more complete Energy consumption statistics system and analysis chart of smelting iron ore, the use of million yuan industrial output value of energy consumption, unit product energy consumption calculation method, the level of energy consumption indicators of metallurgical iron ore for evaluation and evaluation of energy efficiency and energy-saving analysis, to provide a theoretical and Application basis. This paper evaluates the energy structure and energy flow ratio of Yanshan Iron Mine from different angles, determines the trend and problem of energy consumption change, puts forward the solution for the energy management and energy saving evaluation analysis. Through the implementation of the scheme, the energy management level, Improve the efficiency of various energy use has a very good effect..
