After years of development, paste backfill technology has become an important part of China's green safety mine construction and coal green mining technology system in the new era. In this paper, the research status of paste backfill technology in China's coal mines is expounded from the aspects of paste backfill materials, strata control theory, and paste backfill technological process. Based on the statistics of the distribution number of coal mines adopting paste backfill technology, several typical paste backfill mines are listed, and the parameters of backfill panel, geological conditions, and paste backfill effect are analyzed, the general conditions of applying paste backfill technology in coal mines are summarized. Finally, some problems in the application of paste backfill technology are pointed out, and the future development of backfill mining is prospected from the research and development of backfill materials, deep underground backfill mining, intelligent paste backfill, and other aspects. This paper provides a reference for a comprehensive and in-depth understanding of the current development status of paste backfill technology in China.
经过多年的发展，膏体充填技术已成为中国新时代绿色安全矿山建设和煤炭绿色开采技术体系的重要组成部分。本文从膏体充填材料、岩层控制理论和膏体充填工艺三个方面阐述了中国煤矿膏体充填技术的研究现状。基于膏体充填技术在煤矿的分布数量统计，列出了几个典型的膏体充填矿山，并对充填体参数、地质条件和膏体充填效果进行了分析，总结了煤矿膏体充填技术的应用概况。最后，指出了膏体充填技术应用中存在的问题，并从充填材料研发、深部地下膏体充填、智能化膏体充填等方面对未来充填开采的发展进行了展望。本文为全面深入了解中国膏体充填技术的发展现状提供了参考。
