摘要
煤的孔隙结构研究是采空区流体运移规律的重要基础,本文采用CiteSpace引文空间分析法对煤的孔隙相关文献进行可视化分析,发掘该研究领域近年来的研究热点、前沿动态和发展趋势。研究表明:近五年的研究热点有吸附解吸、煤自燃、低阶煤、孔隙特征、分形特征、压汞法、等温吸附、核磁共振等;采空区煤的孔隙研究趋势以煤的孔隙内部结构及特征为发展方向。研究成果为该领域的研究前沿、科学问题确定、研究方向选择提供借鉴。
The study of coal pore structure is an important basis for the law of fluid migration in the goaf.CiteSpace analysis method is adopted in this paper to visually analyze literatures of coal pores,and to explore research hotspots,frontier dynamics and development trends of this research field in recent years.The results show that the research hotspots in the past five years include adsorption and desorption,coal spontaneous combustion,low-order coal,pore characteristics,fractal characteristics,mercury injection method,isothermal adsorption,nuclear magnetic resonance and other related researches and the research trend of coal pores in goaf is based on the internal pores structure and characterizes.The research results provide reference for the research frontier,the determination of scientific problems and the selection of research direction in this field.
