针对底鼓防控在沿空留巷围岩控制中的重要作用,基于系统的文献查阅,对我国沿空留巷底鼓特征、底鼓机理、影响因素及防控技术的研究现状进行归纳总结和分析,并对目前的研究现状加以评述。最后,分析了我国沿空留巷底鼓防控所存在的难题,并对未来的研究方向进行了展望。指出深井大断面沿空留巷是发展趋势,应加大对该类沿空留巷底鼓机理的基础理论研究,积极探索和研究不同岩性底板沿空留巷底鼓机理,构建适合我国国情的沿空留巷底鼓防控体系。
Aiming at the important role of bottom drum prevention and control in the surrounding rock control of gob-side entry retaining, based on the systematic literature review, the author summarizes the research status of bottom drum, bottom drum mechanism, influencing factors and prevention and control technology of gob-side entry retaining system in China. And analysis, and review the current research status. Finally, the problems existing in the prevention and control of bottom-retaining drum for gob-side entry retaining in our country are analyzed, and the future research directions are prospected. It is pointed out that there is a trend of development of gob-side entry retaining for deep section with large section in deep mine. The basic theory of gob-side entry mechanism of gob-side entry retaining should be strengthened. The bottom drum mechanism of gob-side entry retaining with different lithology floor should be actively explored and constructed to suit China’s national conditions Gob-side drift retaining drum prevention and control system.
