摘要
研究了我国西南地区各主要成煤时代、各类型煤中砷的含量及分布特征 ,分析了造成煤中砷富集的主要因素 .结果表明 ,影响砷的迁移、富集的因素主要有物源区母岩、成煤植物、成煤环境、煤化作用和构造运动等 。
The main coal forming periods and the content and distribution of arsenic in coals of different kinds in Southwest China were researched; And the enrichment factors of arsenic in coal was analyzed. The result shows that the factors influencing the migration and enrichment of arsenic are mainly the mother rock of provenance, the coal forming plants and environment, coalification, and tectonic movement. The enrichment of arsenic in coal is the result of geological actions in different periods.
