However, underground coal mine conditions in different regions are complex and changeable, and the flame retardant properties of gel materials vary.

A resistance wire mesh is provided at the bottom of the experimental furnace 1. During the process of heating the coal block, the air supply fan 8 provides oxygen or air to the test coal block to improve the combustion efficiency and reduce the generation of harmful gases. After the experimental furnace 1 heats the test coal block to the specified temperature through the resistance wire mesh, the centrifugal pump 3 is turned on to allow the fire extinguishing material in the gel storage tank 2 to enter the experimental furnace 1. The technician observes the temperature inside the experimental furnace 1 by observing the display screen 11. The gas collector 4 can monitor the gas generated during the experiment and monitor the harmful gases generated. When the concentration of harmful gases is too high, the experiment needs to be stopped to prevent danger.
