为进一步了解我国煤与瓦斯共采领域的整体研究进展，以中国知网（CNKI）数据库作为样本来源，借助Citespace软件绘制出发文量、研究机构以及关键词聚类等知识图谱，对我国煤与瓦斯共采研究状况进行可视化分析。研究表明：在时间分布上，经历了缓慢萌芽期−快速成长期−平稳成熟期3个发展阶段，尤其是在2000—2014年之间开启了该领域快速发展的黄金时代，核心期刊和全部期刊的发文量均得到快速增长，反映出该阶段处于我国煤与瓦斯共采研究的高潮期；在合作网络方面，主要研究机构包括中国煤炭科工集团、中国矿业大学、河南理工大学等机构，均是国内从事煤炭领域研究的重要科研机构；结合关键词聚类和相关文献进行梳理分析，发现我国煤与瓦斯共采研究主要包括数值模拟、瓦斯、采空区和水力压裂等高频关键词，通过提取突现强度较高的前20位关键词，并按照突现年份重新排序，得到突现词随时间推进的演化情况；形成了以煤层增透、水力冲孔、以孔代巷以及碎软煤层等为主要突现关键词成为近年来研究人员高度关注的对象，表征了其是当前的研究热点，并有成为未来发展和关注的研究趋势。在此基础上，利用可视化知识图谱，挖掘研究领域的前沿热点和发展趋势，以期为我国煤与瓦斯共采研究提供科学参考。

In order to further understand the overall research progress in the field of coal and gas co-mining in China, taking CNKI database as the sample source, with the help of Citespace software, the knowledge maps such as the articles published, research institutions and keyword clustering are drawn to visually analyze the research status of coal and gas co-mining in China. The results show that the time distribution has experienced three stages: slow germination period, rapid growth period, and stable maturity period, especially the golden age of rapid development in this field between 2000 and 2014. The number of publications in core journals and all journals has been growing rapidly, which reflects that this stage is at the climax of coal and gas co-mining research in China. In terms of cooperation network, the main research institutions include China Coal Science and Engineering Group, China University of Mining and Technology, Henan Polytechnic University and other institutions, which are important research institutions in the field of coal in China. Combined with keyword clustering and related literature analysis, the research on coal and gas co-mining in China mainly includes high-frequency keywords such as numerical simulation, gas, goaf and hydraulic fracturing. By extracting the top 20 keywords with high burst intensity and reordering them according to the burst years, the evolution of burst words with time is obtained. The keywords such as coal seam permeability enhancement, hydraulic punching, replacing roadways with holes and breaking soft coal seams have become highly concerning to researchers in recent years. It is characterized as the current research hotspot and has become the future development and research trend. On this basis, the frontier hotspots and development trends in the research field are excavated by using the visual knowledge maps, so as to provide scientific reference for the research on coal and gas co-mining in China.
