摘　　要：为解放建筑物下压煤,结合超高水材料的基本性能,研究出超高水材料采空区充填开采技术。该技术包括开放式、袋式、混合式和分段阻隔式4种充填方式,对各种充填方式的充填过程、优缺点及适用条件进行了分析。结果表明:在井下潮湿、低温、封闭的环境中,超高水材料是一种理想的采空区充填材料;该材料及相应的充填开采方法是未来采空区充填开采技术的发展方向之一。Based on the basic properties of super high-water material, the technology of goal filling mining with super high-water material was studied out in order to liberate the coal resources under buildings. There are four types in the technology,including open filling, bag filling, hybrid filling and partition filling. Every type was analyzed detailedly, containing its filling process, advantages, disadvantages and applicable conditions. The results show that super high-wa- ter material is an ideal goaf filling material in a wet, cold and closed environment, and the material with its correspond- ing fill mining methods is one of the development directions of future goaf filling mining technologies.
