山西省煤系伴生三稀矿产资源研究现状及找矿前景

为进一步勘探和开发山西省煤系伴生的稀有、稀土、稀散元素（简称三稀元素）矿产资源，在综合以往研究的基础上，统计了山西省煤系伴生三稀元素的含量和赋存特征，同时结合山西省煤炭资源分布特征探讨了煤系伴生三稀矿产资源的找矿前景。结果表明，山西省宁武煤田平朔矿区为煤系伴生锂超大型矿床，北部煤炭基地部分矿区和西山煤田部分矿区具备煤系伴生锂成矿潜力；宁武煤田北部、大同煤田北部、河东煤田北部及西山煤田局部地区具备煤系伴生镓成矿潜力；沁水煤田和西山煤田山西组含煤岩系的伴生稀土元素均有一定的工业开发利用价值；省内六大煤田含煤岩系中尚未发现其他达到工业利用品位的伴生三稀元素矿床。初步研究成果对指导山西省煤系伴生矿产资源开发、煤炭资源可持续发展和粉煤灰高效利用具有实际意义。 

Status and prospect of research for three type coal-associated rare earth resources in coal measures in Shanxi Province

For further exploration and exploitation of the new kind of mineral resources, the content and occurrence of coal-associated rare earth, rare metals and rare-scattered elements in Shanxi Province were analyzed on the basis of previous research. According to analysis of the distribution characteristics of coal resources in Shanxi, the prospecting potentiality of coal-associated mineral resources was discussed. The results show that the coal measures in Pingshuo mine in Ningwu coalfield are a super large deposit of coal-associated lithium, and coal producing base in northern part of Shanxi Province and local mines in Xishan coalfield may also have the accompanying lithium metallogenic potential. The north of Ningwu coalfield, north of Datong coalfield, north of Hedong coalfield and the local area of Xishan coalfield have accompanying gallium metallogenic potential. There is certain industrial development and utilization value of rare earth elements in Qinshui coalfield and Shanxi Formation in Xishan coalfield. The present study shows that no other elements in coal can achieved the industrial utilization level in all the six coalfields of Shanxi Province. This research has significance to guide the exploitation of mineral resources, sustainable development of coal resources and efficient utilization of fly ash in coal industry of Shanxi Province.
