煤矸石的微区分析--以淮北某煤矿为例

he 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.
