通风阻力测定是井工煤矿通风技术管理的基础工作。由于传统的气压测量仪器（如BJ-1型精密数字气压计）在测点标高发生较大变化时需换挡、扩展测量，仪器间数据误差较大，为保证测量精度，分组测量闭合点成了不二选择。该文提出了由于高精度、大量程仪器的出现使得闭合点可以非闭合测量，对矿井通风阻力测定工作是一种变革。

The measurement of ventilation resistance is the basic work of the ventilation technology management of well coal mine. Due to the traditional pressure measuring instruments (such as BJ-1 type precision digital pressure gauge) need to shift gears, extended measurement when the measuring point elevation changed greatly, which caused the larger error data between the instruments, in order to ensure the measurement accuracy, the closing point is into the only choice in grouping measure. In this paper, a new method is proposed for measuring the resistance of the mine ventilation.
