摘　　要：根据邢台煤矿实际情况,对粉煤灰膏体充填材料及其选择依据、粉煤灰膏体的配比及其依据等相关问题进行了分析,对充填材料的物理化学性质进行了测定。在满足邢台煤矿要求的情况下确定了充填材料的最优配比范围,并对影响配比的因素进行了分析,可为煤矿膏体充填不迁村采煤技术的应用提供借鉴。In this paper, analysis was made on the fly ash paste filling material, the selection basis and proportioning of flyash paste according to the actual situation of Xingtai Coal Mine, and the physicochemical properties of the paste filling materialwere measured. The optimum proportioning of the filling material which can meet the requirements of the mine was determined, Inaddition, analysis was made on the factors affecting its proportioning, this fly ash paste filling technology can be used for referencein coal mining under villages.
