description The invention discloses a method for evaluating the stability of coal-oil slurry. The method comprises the following steps: 1) injecting prepared and uniformly stirred coal-oil slurry into a special coal-oil slurry sampler; (2) standing the sampler filled with the uniform coal-oil slurry at a constant temperature, and then quickly freezing the sampler to solidify the coal-oil slurry in the sampler; (3) loosening the clamping sleeve of the frozen sampler, detaching a semi-cylinder, keeping the position of the solidified coal-oil slurry in the other semi-cylinder unchanged, cutting solidified coal-oil slurry samples at the lower parts of all equal sections along all bisectors and sampling lines, and respectively measuring the content of toluene insoluble substances in the samples according to a unified standard method; and 4) calculating stability parameters. According to the method, the stability of the coal-oil slurry can be quantitatively described, then the stability of different coal-oil slurry can be quan
