Research focus and evolution of coal and gas outburst and fault control:a visual analysis based on CiteSpace

为了解国内、外关于断层构造对瓦斯突出控制作用的研究概况,以2000~2022年CNKI和Web of Science期刊库为基础数据,利用CiteSpace软件构建知识图谱,梳理煤与瓦斯突出与断层控制作用发展脉络,可视化表达其研究热点。研究表明:结合关键词进行分析,煤与瓦斯突出发生机理研究主要集中于瓦斯、应力与构造煤方面,且构造煤和瓦斯抽采为高度关注的对象,表征其是当前的研究热点;断层构造-突出发生机理目前主要研究断层带瓦斯和应力特征以及构造煤和构造特征,现场预测防治方面则依赖于主控因素、敏感指标及实时预警方面的探究;在时间分布上,突出机理研究在2000~2015年间快速发展,以构造煤及构造因素的定量分析研究为主;突出预测防治方面有明显发展,防治技术手段更加先进且多样化;断层带突出防治措施方面有较大的进步,出现了更加系统综合的突出防治措施及预测方法。在可视化分析基础上,深入研究煤与瓦斯突出领域前沿热点和发展趋势。

In order to understand the general situation of domestic and foreign research on the control effect of fault structures on gas outburst,based on CNKI and the Chinese and English journal database of Web of Science from 2000 to 2022,CiteSpace software is used to construct knowledge map,and the relevant research hotspots are visualized.The research shows that combined with the analysis of keywords,the research on the mechanism of coal and gas outburst mainly focuses on gas,stress and tectonic coal,and tectonic coal and gas drainage are highly concerned objects,which are the current research hotspots.The fault structure-outburst mechanism At present,the gas and stress characteristics of the fault zone and the structural coal and structural characteristics are mainly studied.The on-site prediction and prevention depends on the main control factors,sensitive indicators and real-time early warning.In terms of time distribution,the research on the prominent mechanism developed rapidly from 2000 to 2015,mainly focusing on the quantitative analysis of tectonic coal and tectonic factors.There are obvious developments in the prevention and control of outburst prediction,and the prevention and control techniques are more advanced and diversified;great progress has been made in the prevention and control measures of fault zone outburst,and more systematic and comprehensive prevention and control measures and prediction methods have emerged.On this basis,it is expected to provide reference for further research in the field of coal and gas outburst.In order to understand the general situation of domestic and foreign research on the control effect of fault structures on gas outburst,based on CNKI and the Chinese and English journal database of Web of Science from 2000 to 2022,CiteSpace software was used to construct knowledge map,and the relevant research hotspots were visualized.The research status and development direction of gas outburst,especially considering the occurrence mechanism of fault zone outburst,are analyzed.The results show that the research in the field of coal and gas outburst can be roughly divided into coal and gas outburst mechanism research and coal and gas outburst prediction and prevention.The research directions of Chinese and English journals are different,and the literature on Web of science mainly focuses on mechanism research.The main research direction of the occurrence mechanism of fault structure-outburst is the characteristics of gas and stress as well as structural coal and structure in fault zone.The field prediction and prevention depends on the main control factors,sensitive indicators and real-time early warning.The study of outburst mechanism from 2000 to 2015 was mainly based on quantitative analysis of structural coal and structural factors,but in recent years,the related research is slightly less.Highlighting the significant development in forecasting and control,highlighting the more advanced and diversified prevention and control technology;Great progress has been made in the prevention and control measures of fault zone outburst,and more systematic and comprehensive prevention and control measures and prediction methods have appeared.The research on the mechanism of fault-outburst is still mainly concentrated in 2000-2018,and there are few related researches in recent years.On this basis,it is expected to provide reference for further research in the field of coal and gas outburst.
