摘要
基于平差原理,本文给出了在矿井通风阻力测定中对风网阻力测定值进行系统平差的一般方法。平差计算结果表明,针对给定的精度控制窗口,该法具有较好的收敛性。
Based on the adjustment fundamentals, this Paper Presents the goneral method of systematic adjustment for the resistance values determined in mine ventilation networks、The adjustment results show that the method is imbued with a better convergoncy for a given Precision control criterion
