摘要
本文研究了砷和氟在利西恰恩斯克地质工业区域分布的特征,在煤层的基本层位和岩系中完成了浓度加权平均数计算。通过聚类分析,查明了岩层的结构特征和后生成矿作用,分析了有害元素积聚的成因及浓度相关性。
Cluster analysis is an important method for evaluating the characteristics of coal.By weighted average and cluster analysis,the concentration distribution of the arsenic and the fluoride is studied in the coal layer and rock series in Lixiqiens to identify the structure characteristics of the rock and epigenetic mineralization,analysis the accumulation causes and the concentration relevance of harmful elements each other.
