Abstract：In this paper, analysis was made on the fly ash paste filling material, the selection basis and proportioning of fly ash paste according to the actual situation of Xingtai Coal Mine, and the physicochemical properties of the paste filling material were measured. The optimum proportioning of the filling material which can meet the requirements of the mine was determined, In addition, analysis was made on the factors affecting its proportioning, this fly ash paste filling technology can be used for reference in coal mining under villages.
