煤矸石综合利用知识图谱可视化分析

Visual analysis of mapping knowledge domains for comprehensive utilization of coal gangue

为落实“十四五”推动大宗固废综合利用的要求,推进我国矿山绿色智能高质量发展,提高煤矸石综合利用率是其中最重要的途径和内容之一。为更加全面地了解目前煤矸石综合利用的热点与发展方向,以中国知网(CNKI)数据库为样本源,利用Citespace软件对2005-2021年收录的有关煤矸石综合利用领域的930篇文献进行了知识图谱构建与分析,结果表明:近年来该领域的发文量有所减少,原因可能是煤矸石综合利用技术进入了瓶颈期;研究者数量较多,但合作较少;研究热点主要集中在“循环经济”“充填开采”“抗压强度”等方面;未来,煤矸石的综合利用要坚持走“因地制宜、积极利用”的路线,继续加强对煤矸石组分、结构、特性等方面的基础研究。

To implement the 14th Five-Year Plan with requirements for comprehensive utilization of bulk solid wastes and advancing high-quality development of green and intelligent mines,by which the improvement on the utilization efficiency of coal gangue was one of the critical approaches and subjects.For a full understanding of current research focus/interest and development direction of comprehensive utilization of coal gangue,China National Know-ledge Infrastructure(CNKI)database was taken as the sample source,using Citespace software and based on 930 papers collected from 2005 to 2021 in the field of comprehensive utilization of coal gangue,mapping knowledge domains were constructed and studied.The results indicated the reason why the number of relevant papers had dropped in recent years was the technical bottleneck that researchers working on the comprehensive utilization of coal gangue encountered.Little cooperative programs were conducted by so many researchers.The research interests in this field were focused on"circular economy","filling mining","compressive strength"and so on.In the future,the comprehensive utilization of coal gangue should be adhered to the route of"adjusting measures to local conditions for active utilization",and continuous enhancement on the fundamental research on the composition,structure and characteristics of coal gangue.
