摘要
对用不同方法现场测定矿用主要通风机风压产生的测量误差进行了对比分析，指出直接测定风压法具有相对误差小的优点。
Abstract Contrast analysis was conducted for errors in field measurement of ventilating pressure of mine main fan by different methods.It was proposed that the direct measurement of ventilating pressure provides the advantage of less relative errors.
