【摘要】 铁矿资源开采和选矿过程产生的铁废石和尾矿是影响铁矿行业可持续发展的主要固体废弃物。随着铁矿资源的大量开采和选矿,产生的大量铁废石和尾矿对矿区生态、周边大气、地下水及土壤产生了巨大的危害,急需开展资源化利用和绿色矿山建设。作者结合多年来从事地质材料与工程、尾矿资源综合利用及绿色矿山建设的研究经历,分别介绍了铁矿废石和尾矿在砂石骨料、混凝土、3D打印、路基、建筑材料、有价组分回收、石塑复合板材、尾矿复合肥及矿山地质生态复垦等方面的资源综合利用与新材料的研究、开发及工程应用。在分析国外绿色矿山建设法律法规的基础上,根据国家自然资源部行业绿色矿山建设规范要求,论述了铁矿行业尾矿固废资源化利用与绿色矿山建设的必要性,并对绿色矿山建设提出建设性意见。更多还原

【Abstract】 Iron ore wastes and tailings form iron ore mining and processing are the main solid wastes impacting the sustainable development of iron ore industry. Large quantity of iron ore wastes and tailings impact mine ecology, atmosphere, underground water and soil, which need to be used and to construct green mines. This paper gives a general introduction to comprehensive use of iron ore wastes and tailings on sandstone, concrete, 3 D printing, road, building materials, recycling and stone-plastic compound material, tailing fertilizer and mine ecological rehabilitation, new material research, development and engineering application. Based on review of laws of foreign green mine construction, this paper discusses the necessity of use of iron ore wastes and tailings and green mine construction and presents constructive suggestions for green mine construction.更多还原
