Abstract: 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.
