The utility model discloses a basalt spunlaced filter felt with a resistance to high temperature and is characterized in that basalt fibrous layers are bonded on the upper and the lower surfaces of a basalt base fabric by the high-pressure water flow jet process. The utility model has the advantages that the basalt spunlaced filter felt has flat and smooth surfaces, and is resistant to high temperature and mainly applied to the filter materials which work in a high temperature environment (200 to 3500 DEG C) and in a ultrahigh temperature environment (above 5000 DEG C); the operating temperature of the basalt spunlaced filter felt is 5000 DEG and the instantaneous service temperature is 6500 DEG C; the basalt spunlaced filter felt has a corrosion resistance, a water resistance, a high filter efficiency and a heat-insulation property and is excellent in filtering performance and flame retardancy; and the basalt spunlaced filter felt has good dimension stability, high tensile breaking strength, good flexibility, a good wear resistance and a long service life.
