The colloidal layer index measuring method is designed by simulating the coking conditions of an industrial coke oven. The coal sample is placed in a steel cup, is added with constant pressure and is heated from one side of the bottom surface. The steel cup is put into a refractory brick with holes of a certain specification and technical index, the temperature is raised at a certain heating speed, and the temperature transferred into the cup is gradually increased from top to bottom. Because the surrounding heat dissipation conditions are better when the coal cup is heated by a single side, a series of isothermal surfaces with the temperature descending from bottom to top are formed in the coal sample in the coal cup. When the coal sample is heated to a certain temperature, the uppermost coal sample does not have softening temperature yet, so the coal sample is kept unchanged, and the middle part of the coal sample is changed into asphalt colloid-colloid body due to the softening temperature; the lower part of the gel body becomes semi-coke due to reaching the curing temperature. Therefore, the semicoke layer, the colloidal layer and the un-softened coal sample layer 3 part are formed in the coal sample, and the whole process of the colloidal layer index measurement is realized.
