中文摘要：

设计和提出一种测定矿井巷道火灾时期火区阻力和火区风量的实验装置和方法,根据通风能量方程和能量守恒定律分别推导出火区阻力和火灾巷道测点断面平均风速的计算公式,给出火区烟流平均速度和火区风量的测定方法.实验测定结果表明：火灾时期火区阻力与火区风量均与时间呈二次曲线关系,但火区阻力与火区风量随时间的变化趋势正好相反,即当火区阻力增大时,火区风量就减小;当火区阻力减小时,火区风量就增大.

英文摘要：

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.
