This article summarizes the development status and successful application experience of backfill mining in Hunan province, and analyzes the situation of backfill mining at home and abroad. It also evaluates the development trend of backfill mining technology and the key technical problems that should be solved. Finally, it is concluded that in underground mines where resource utilization and environmental protection are coordinated, backfill mining technology will be given priority for development. China has entered a peak period of mineral resource consumption, and the mining industry is facing geological disasters such as deep rock bursts and rockburst; Ecological and environmental issues such as surface subsidence and subsidence; Technical and economic issues such as production capacity and production costs. Due to the discharge of a large amount of industrial wastewater, waste materials, and exhaust gases, the natural ecological environment has deteriorated. People are increasingly aware of the importance of strengthening mining environmental protection and comprehensive utilization of mineral resources, and there is an urgent need to achieve green mining. Backfilling mining technology is the main supporting technology for green mining.湖南充填工业泵、工业充填泵本文总结了充填采矿的发展现状历程与成功应用的经验，并且分析了国内外充填采矿的情况，对矿山充填采矿技术发展趋势和所应解决关键技术问题进行了评述。最后得出在资源利用和环境保护协同并进的地下矿山，充填采矿技术必将得到优先发展。 我国已进入矿产资源消耗的高峰期，而采矿业面临深部岩爆、冲击地压等地质灾害问题；地表下沉、塌陷等生态环境问题；生产能力、生产成本等技术经济问题。由于大量工业废水、废料、废气的排放造成了自然生态环境的恶化，人们越来越认识到加强矿山环境保护和矿产资源综合利用的重要性,迫切需要实现绿色采矿,而充填采矿工艺便是绿色采矿的主体支撑技术。
