摘　　要：陶一煤矿面临着"三下"压煤问题。陶一煤矿利用超高水材料进行采空区充填,以开采"三下"呆滞煤炭资源。超高水材料浆体水的体积达到95%～97%,因此其灌注特性较好。超高水材料开放式充填能够达到较高的充填率。通过开掘观测巷道、钻孔等手段进行矿压监测,表明该工艺可以缓解矿压显现程度,浆体能够灌注到老空区裂隙及矸石周围,胶结效果较好。In Taoyi Mine, there exists a problem of ＂three unders＂ mining. In order to explore the dead ＂three unders＂ coal resources, Taoyi Mine adopts ultra-high-water material to fill the goal. The slurry water volume of ultra-high-water material reaches 95%-97%, so it has good perfusion characteristics. The open filling with ultra-high-water material can reach higherfilling rate. The results of strata control observation by excavating roadway, drilling and other means for observing the filling effect show that this technique can alleviate the strata behavior de-gree, and the slurry can be grouted in fissures in old goal and around gangue, and it has a good cementation effect.
