煤中伴生微量元素的研究是煤炭清洁高效利用的热点和前沿方向，对于六盘水市煤炭行业转型具有重要的战略意义。为系统分析六盘水矿区煤中伴生元素含量状况，促进煤炭的综合利用，拓展传统煤炭利用发展方向，通过对典型煤矿向斜进行采样，采用电感耦合等离子体发射光谱仪进行样品分析，试验结果与《 矿产工业要求参考手册 》比对。结果表明，该矿区伴生元素利用受限制，含量普遍偏低，工业利用价值不高。因地质环境差、煤层厚度薄、元素在煤中赋存状态不清晰等因素，此次试验未发现达到工业开发品位的矿床。结合当前我国煤中金属元素矿产资源前沿研究存在的问题，对六盘水市煤中金属元素的研究提出下一步方向，建议加强煤中金属元素测试技术和赋存状态的研究，对各煤层的伴生元素含量情况要进行动态普查。

The study of associated trace elements in coal is a hot spot and frontier direction of clean and efficient utilization of coal, which is of great strategic significance for the transformation of coal industry in Liupanshui City. In order to systematically analyze the content of associated elements in coal in Liupanshui mining area, promote the comprehensive utilization of coal, and expand the development direction of traditional coal utilization, the typical coal mine syncline was sampled, and the samples were analyzed by inductively coupled plasma emission spectrometer. The test results were compared with the ' Mineral Industry Requirements Reference Manual '. The results show that the utilization of associated elements in the mining area is limited, the content is generally low, and the industrial utilization value is not high. Due to factors such as bad geological environment, thin coal seam thickness, and unclear occurrence of elements in coal, no deposits that meet the industrial development grade were found in this test. Combined with the problems existing in the frontier research of metal element mineral resources in coal in China, the next direction of the research on metal elements in coal in Liupanshui City is put forward. It is suggested that the research on the testing technology and occurrence state of metal elements in coal should be strengthened, and the content of associated elements in each coal seam should be dynamically surveyed.
