Abstract：The experimental device and method used for measuring the fire resistance and fire air quantity during mine fire were designed and proposed, the calculation formulas for the fire resistance and the average air velocity in the test point section in fire roadway were derived according to the ventilation energy equation and the energy conservation law, and the measuring methods for the average smoke flow velocity and air quantity in the fire area were given. The experimental results indicated that the fire resistance and the fire air quantity were all in a quadratic curve relationship in the fire period; but the change trend of the fire resistance and the fire air quantity with time was just opposite, namely, when the fire resistance increased, the fire air quantity decreased, and when the fire resistance decreased, the fire air quantity increased.
