摘　　要：为了调查研究山西省六大煤田石炭-二叠纪主采煤层煤中铀的含量与分布特征,在山西省六大煤田选取代表性矿井采取了若干样品,通过光学显微镜、扫描电镜、X射线粉末衍射和电感耦合等离子体质谱等技术对这些样品进行分析,再结合以往钻孔测试数据,经研究发现:高平矿区及寿阳矿区出现铀的富集区;垂向分布上看太原组主采煤层煤中铀的含量高于山西组;煤中铀的含量与灰分、硫分正相关,相关系数分别为0.429、0.544。To investigate the uranium content and distribution of the Carboniferous and Permian main mining coal seams in Shanxi province, collected some samples from several representative coal mines in six major coalfields of Shanxi province. Multiple analysis were conducted on these samples using optical microscope, scanning electron microscopy, X-ray powder diffraction and inductively coupled plasma mass spectrometry. Together with data of previous drill hole, uranium enrichment areas were identified in Gaoping and Shouyang mining areas. The characteristics of vertical distribution display that the uranium content of main mining coal seam of Taiyuan group is higher than that of Shanxi group. There is positive correlation between the uranium content and ash and sulfur content of the coal,while the correlation coefficients are 0.429 and 0.544, respectively.
