根据野外地质特征结合中子活化成分分析结果，探讨了黔西南高砷煤的分布特征、影响因素和某些地球化学特征。高砷煤严格受构造（褶皱和断层）、地层（二叠系龙潭组）、沉积相（海陆交互相）的控制，分布于平行背斜长轴的断层两侧，愈靠近断层面砷的含量愈高。砷在煤中的分布极不均匀，即使同一煤层变化也极大。在时空关系与元素组合上高砷煤与区内卡林型金矿密切相关。
Based on the field geologic characteristics and neutron activation analysis, the distribution characteristics, influential factors and some geochemical characteristics of high-arsenic coal in southwestern Guizhou were discussed. High arsenic coal is strictly controlled by structures (folds and faults), stratigraphy (Permian Longtan Formation) and sedimentary facies (sea-land interaction facies), and is distributed on both sides of the fault parallel to the long axis of the parallel anticlines. The higher. The distribution of arsenic in coal is extremely uneven, even though the same coal seam varies greatly. High-arsenic coal is closely related to Carlin-type gold deposits in the space-time relationship and elemental assemblage.
