摘　　要：煤矿“三下”压煤开采是我国煤炭开采面临的开发难点,而超高水材料因其自身优势,可用于充填煤矿采空区,从而解决“三下”压煤开采难题。介绍了超高水材料的特性,阐述了开放式、全袋式、混合式等超高水材料充填采空区常用的充填方法及其优缺点等,介绍了超高水材料在充填采空区的应用实践,结果表明该技术可行性高、充填成本低、安全性较高、可以延长矿井寿命等。"Under-three"trapped coal mining(coal mining under buildings,railways and water bodies)was difficult in China.Because of its own advantages,ultra-high water material could be used to fill the goaf of coal mine,so as to solve the"under-three"trapped coal mining challenges.The characteristics of ultra-high water materials were introduced,and the commonly used filling methods and their advantages and disadvantages of open type,full bag type and mixed type ultra-high water materials for filling the goaf were elaborated.The application of ultra-high water material in filling the goaf showed that this technology had high feasibility,low filling cost,high safety and could prolong the service life of the coal mine.
