The invention discloses a hole sealing material. The hole sealing material comprises the following raw materials in percentage by weight: 50-70% of sulphate aluminium cement, 5-15% of gypsum, 5-15% of coal ash, 5-15% of aluminum oxygen chamotte, 0.5-1% of a water reducer, 0.3-0.7% of calcium stearate and 0.2-1.0% of a foaming component. The invention further discloses a preparation method for and a using method of the hole sealing material. The hole sealing material is applied to gas extraction hole-sealing; and the hole sealing material is short in coagulation time, free of shrinkage, long in a continuous expansion period, high in strength and good in foaming and sealing performance.
