The utility model provides a coal field conflagration evolutionary process simulation test test device includes gas supply part, physical similarity simulation portion, the portion of igniting, data acquisition and analysis portion, the portion of lifting by crane. The utility model discloses in, experimental box forms for the standard component preparation of low price, this coal field conflagration evolutionary process simulation test test device low price. The utility model provides an adjustable angle of inclination of coal field conflagration evolutionary process simulation test test device and air feed oxygen concentration, test conditions corresponds to reality more, has improved the precision of physical similarity analogue test result. Because the utility model discloses in, physical similarity analogue test just can collect multiple data such as stress among the combustion processes of coal seam, temperature, crack growth, gaseous volume?change, the change of flue gas composition, need not carry out different experiments to different types of data, has saved testing expenses.
