煤矸石的微区分析——以淮北某煤矿为例

煤矸石的大量排放和堆积,严重的占用了我国的国土资源、污染林地,不仅给地球生态环境带来了恶劣的危害,也造成了本就稀缺的矿产资源巨大的浪费和损失。充分利用煤矸石、提取其中有价元素对我国环保事业和经济可持续发展有重要意义。实验选择淮北市某煤矿的煤矸石为样本,研究煤矸石的物理学结构、矿物成分和化学组成确定其煤矸石类型,为提取其中有用的金属元素提供物质基础,进而为淮北地区各级政府部门制定有关矿区土壤的保护和生态修复以及提高煤矸石利用率的政策方法、计划提出科学依据。

The massive discharge and accumulation of coal gangue seriously occupy the land resources of our country and pollute the forest land.It not only brings bad harm to the ecological environment of the earth,but also causes huge waste and loss of the scarce mineral resources.Therefore,it is of great significance to make full use of coal gangue and extract valuable elements from it for China's environmental protection and sustainable economic development.In this experiment,coal gangue from certain Coal Mine in Huaibei City is selected as the research sample to study the physical structure,mineral composition and chemical composition of coal gangue and determine its type of coal gangue,so as to provide material basis for the extraction of useful metal elements.Furthermore,it provides scientific basis for the government departments at all levels in Huaibei area to formulate policies,methods and plans for soil protection and ecological restoration in mining areas and for improving the utilization rate of coal gangue.
