摘要
通过对平顶山矿区煤矸石的微量营养元素、粒度与酸碱度及煤矸石中的有害元素的分析测定,在综合国内外煤矸石研究资料的基础上,笔者认为平顶山矿区煤矸石可用作农肥。煤矸石的这种用途不仅可获得较大的经济效益,而且还具有明显的社会效益和环境效益。
A rare amount of nutrilious elements, particle size, pH and poisonous elements in the gangue from Pinding Mountain were determined. Results show that the gangue can be used as fertilizers. It brings about a great deal of both economical efficency and social and environmental efficiencies to convert gangue, a waste, into useful materials, fertilizers.
