Abstract

With a view to comprehensive processing of coal and its ash and slag wastes, the metallogenic specialization of Kuznetsk Basin coal is assessed for different geological and economic regions and for coal of different metamorphic stages. The content of nonferrous and rare metals in Kuznetsk Basin coal and Kazakh coal is compared. The prospects for extracting valuable metals from coal and, in particular, its waste are assessed. Nonferrous and rare metals may accumulate in the initial coal (the syngenetic factor) and coal may be associated with the action of metal–hydrogen–carbon fluids on tectonically permeable sections of the coal bed (the endogenetic factor). In addition, elevated metal content in the coal may be associated with the proximity of several coal fields (the epigenetic factor). In the Kuznetsk Basin, the endogenetic and epigenetic factors are most significant. The metamorphic stage of the coal has less effect on the metal content. Metals present in low concentrations are most often the result of accumulation in the initial coal (the syngenetic factor). The content of toxic metals in the coal is below the limiting permissible concentration.

库兹涅茨克盆地煤成矿专业化

摘要

以煤及其灰渣废渣综合加工为目标，针对不同地质经济区域和不同变质阶段的煤，对库兹涅茨克盆地煤的成矿专业进行了评估。比较了库兹涅茨克盆地煤和哈萨克煤中有色金属和稀有金属的含量。评估了从煤中提取有价值金属的前景，特别是从其废物中提取的前景。有色金属和稀有金属可能在初始煤中富集（同生因素），煤可能与金属-氢-碳流体对煤层构造可渗透部分的作用有关（内生因素）。此外，煤中金属含量的升高可能与邻近几个煤田有关（表观成因）。在库兹涅茨克盆地，内遗传和表观遗传因素最为显着。煤的变质阶段对金属含量的影响较小。以低浓度存在的金属通常是初始煤中积累的结果（同源因素）。煤中有毒金属的含量低于极限允许浓度。
