Visualization analysis of research status on coal-rock mass fracturing technology in China based on CiteSpace and VOSviewer

  • 摘要: 致裂技术是实现煤岩性质弱化、卸压增透的有效方法,对于保障矿井安全生产具有重要意义。为了解我国煤岩体致裂技术的整体研究进展,选取1990—2024年中国知网(CNKI)收录的3 388篇相关文献,提取发文量和期刊数据绘制发文情况统计图。随后,使用CiteSpace绘制作者和机构合作网络图、关键词共现与聚类图,最后进行爆发词探测;同时,使用VOSviewer绘制密度视图,从而对该领域的研究状况进行全面的可视化分析。研究表明:我国在该领域的研究经历了缓慢发展期、快速发展期和稳定发展期三个时期,以《煤炭科学技术》、《煤矿安全》、《煤炭学报》等期刊为主要交流平台;核心作者包括林柏泉、刘泽功、倪小明等,核心机构包括中国矿业大学、中国矿业大学(北京)、中煤科工西安研究院(集团)有限公司等,机构间的合作力度较弱;水力压裂、煤层气、瓦斯抽采、冲击地压、数值模拟等是该领域的高频关键词;深部煤层气、切顶卸压、沿空留巷、厚硬顶板、围岩控制、煤系气是爆发至今的关键词,是当前研究的热点,有望在未来延续爆发的趋势,其中,深部煤层气的开采和切顶卸压是当前研究的前沿,是致裂技术主要的应用领域;以水力压裂为首的传统致裂手段存在明显的局限性,新型致裂技术的应用尚不成熟,数值模拟是重要的研究方法。随着煤矿开采的深入,诸如深部高地应力、低渗煤层致裂难度大、水力压裂耗水量大等问题需要进一步解决。将来,我国煤岩体致裂技术,有望在单一技术进步的基础上,向复合致裂的方向发展,以追求成本、效果、环保等多因素的平衡。

     

    Abstract: Fracturing technology is an effective method for weakening coal-rock properties and achieving pressure relief and permeability enhancement, holding significant importance for ensuring coal mine safety production. To understand the overall research progress of coal-rock mass fracturing technology in China, 3,388 relevant publications from the China National Knowledge Infrastructure (CNKI) database (1990—2024) in this field were selected. Data on publications and journals were extracted to create statistical charts of publication trends. Subsequently, CiteSpace was used to generate collaboration network maps of authors and institutions, keyword co-occurrence and clustering maps, and to detect burst keywords. Meanwhile, VOSviewer was employed to produce density view, enabling a comprehensive visual analysis of the field. The research indicates that studies in this area in China have undergone three stages: slow development, rapid development, and stable development. Journals such as Coal Science and Technology, Safety in Coal Mines, and Journal of China Coal Society serve as the main platforms for academic exchange. Core authors include Lin Baiquan, Liu Zegong, and Ni Xiaoming, among others. Core institutions include China University of Mining and Technology, China University of Mining and Technology (Beijing), and China Coal Technology and Engineering Group (CCTEG) Xi’an Research Institute (Group) Co., Ltd., etc. Inter-institutional collaboration remains relatively weak. high-frequency keywords in this field include hydraulic fracturing, coalbed methane, gas drainage, rock burst, and numerical simulation. Keywords such as deep coalbed methane, pressure relief by roof cutting, gob-side entry retaining, thick hard roof, surrounding rock control, and coal measure gas have burst onto the scene and remain hot topics, with the potential to sustain this trend in the future. Among these, the extraction of deep coalbed methane and pressure relief by roof cutting represent the current research frontiers and are the primary application areas of fracturing technology. Traditional fracturing methods, led by hydraulic fracturing, have obvious limitations, while the application of new fracturing technologies remains immature. Numerical simulation serves as an important research method. As coal mining progresses to greater depths, challenges such as high in-situ stress in deep mining, difficulties in fracturing low-permeability coal seams, and high water consumption in hydraulic fracturing need further resolution. In the future, China’s coal-rock fracturing technology is expected to evolve from singular technological advancements toward composite fracturing methods, aiming to balance factors such as cost, effectiveness, and environmental sustainability.
