摘　　要：为系统调查山西省石炭-二叠纪主采煤层煤中锂的含量与分布特征,在全省六大煤田生产矿井系统布设采样点,通过分析测试,经综合分析显示,山西省石炭-二叠纪煤中锂的含量均值较高,整体上太原组含量高于山西组,其中太原组为58.41×10-6、山西组为50.46×10-6;平面展布上,两组煤由北到南整体都呈低-高-低的变化趋势;沁水煤田太原组主采煤层存在两个煤伴生锂矿成矿潜力区,分别位于煤田东北端寿阳-阳泉一线和东南端高平-晋城一线。初步研究成果对指导山西省煤中伴生锂资源进一步的勘探开发以及煤炭资源可持续发展具有实际意义。To systematically investigate Permo - Carboniferous main mineable coal seams lithium content and distribution features in the Shanxi Province has laid out systematic sampling points in operating coalmines of six major coalfields in the province. Through analysis and testing, the comprehensive analysis has shown that the mean lithium content is all rather high in coal. As a whole, lithium content in the Taiyuan Formation is higher than in the Shanxi Formation, the former is 58. 41 ppm, the later 50. 46ppm; on the plan, from north to south in coal of both formations presents a low - high - low variation trend. In the Qinshui coalfield, Taiyuan Formation main mineable coal seams have two metallogenic potential areas of coal associated lithium ore, situated in both northeast end Shouyang - Yangquan line and southeast end Gaoping - Jincheng line in the coalfield. The initial studied results have practical significance to guide further exploration and exploitation of coal associated lithium resources, as well as coal resources sustainable development in the prov-ince.
