运用反射偏光显微镜和扫描电镜等手段研究霍林河14 #煤中矿物分布特征,运用浮沉实验和煤岩组分定量统计方法研究了煤中6种微量元素的分布赋存特征以及有机亲和性.结果表明,霍林河14 #煤中矿物含量较高,以伊利石黏土矿物为主;霍林河煤中微量元素As,Cr和Hg含量较高,Pb,Cd扣Se含量较低;元素As,Cr,Hg和Pb明显富集于矿物中,主要为无机态,与有机组分亲和性较低,而元素Cd和Se与有机组分亲和程度比其他4种元素高,基本上均匀分布于有机组分和矿物中.
Mineral distribution in 14# Huolinhe coal was studied by means of reflection polarizing microscope and scanning electron microscopy (SEM). Float-sink analysis and maceral quantitative statistical method were used to study the distribution, occurrence and the organic affinity of 6 trace elements in 14# Huolinhe coal. The results show that the mineral content is higher in 14# Huolinhe coal, mainly illite clay minerals; content of trace elements As, Cr and Hg in coal is higher, other three trace elements on the contrary; trace elements As, Cr, Hg, Pb are enriched in minerals conspicuous, mainly for the inorganic state, and the organic affinity is low, the organic affinity degree of trace elements Cd, Se is higher than other 4 trace elements, trace elements Cd and Se basically uniform distribution in organic and mineral components.
