摘　　要：开采沉陷是煤炭资源井工开采所面临的主要环境地质问题,其中松散层变形是东部高潜水位矿区生态修复和西部生态脆弱区保护所关注的重点,获得沉陷变形参数对推动开采减损、生态环境保护与修复有着重要的指导意义。借助CiteSpace文献计量软件,基于中国知网(China National Knowledge Infrastructure,CNKI)数据库进行可视化分析,通过对该研究方向近30年主要研究力量、研究热点和现状趋势量化统计与分析,详细地阐述了该方向的研究现状,简要概述了沉陷成因、理论分析、室内试验、数值模拟及原位实测等方面开展的研究内容。从多学科交叉促进理论研究发展、多方法联合建立高精度动态监测、发展与创新测试装备和技术等方面对其未来趋势进行了展望,提出“空-天-地-孔”一体化监测平台的建设与运营,以期通过多维度、网格化立体数据的获取,进一步掌握松散层内部变形特征与传递机理,为实施“源头控制”和“过程治理”理念和评价废弃矿井CO_(2)封存地质条件提供基础数据与科学支撑。Ground subsidence resulting from underground coal mining poses a significant environmental geology challenge in coal resource exploitation.The acquisition of subsidence deformation parameters is crucial for guiding efforts aimed at mitigating mining-induced damage and preserving the ecological environment.Focusing on deformation of the loose layer,which holds particular importance for ecological restoration in high groundwater level coalfields in eastern China and environmental protection in ecologically fragile areas in the west.With the help of CiteSpace bibliometric software and based on the China National Knowledge Infrastructure(CNKI) database,visual analysis was conducted.Through quantitative statistics and analysis of the main research forces,hotspots,and current trends in this research direction over the past 30 years,the current research status of this direction was elaborated in detail.A brief overview of the causes of subsidence,theoretical analysis,indoor experiments,and research on numerical simulation and in-situ measurement.The future trend was forecasted from the aspects of multi-disciplinary promotion of theoretical research and development,multi-method joint establishment of high-precision dynamic monitoring,development and innovation of test equipment and technology,etc.,and the construction and operation of “space-space-ground-hole” integrated monitoring platform was proposed,in order to obtain multi-dimensional and grid three-dimensional data.To further master the deformation characteristics and transfer mechanism of the loose layer,and provide basic data and scientific support for the implementation of “source control” and “process control” in mining and mining area environmental management concept and evaluation of the geological conditions of CO_(2) sequestration in abandoned mines.
