Visualization Study of Knowledge Graph in Hydraulic Fracturing Field Based on Citespace

To explore the research status, cutting-edge trends, and overall development context of hydraulic fracturing technology in China's mining engineering field from 2013 to 2022, this study takes the CNKI database as the data support and uses Citespace software to map the research authors, institutional cooperation networks, as well as keyword clustering and bursts, thereby conducting a visual analysis of relevant literature.The results show that the number of publications in this field during the same period presents an "N"-shaped change across three stages, namely rapid growth, slow decline, and slow recovery in sequence; the types of research institutions are diversified, yet the cooperation tightness is insufficient and the development gap is significant; the core research focuses on directions such as hydraulic fractures, gas extraction, and natural fractures; by sorting out high-burst keywords by year, it is found that permeability enhancement, volume fracturing, and other topics have become research hotspots in recent years, and are highly likely to continue as key research focuses in the future. These results can provide a reference for the subsequent research of this technology in the field of mining engineering.
