矿井通风网络阻力测量相关条件平差

The Correlated Adjustment of Condition Equations for Resistance Measurement of Mine Ventilation Network

本文基于矿井通风网络风流流动的基本定律，论证了目前矿井通风网络阻力测量间接平差模型［１］求解中存在的问题；运用最小二乘法平差原理［２］，建立了矿井通风网络阻力测量的相关条件平差新模型，并提出了求解该模型的计算方法和程序。最后，用一实例加以说明。

Based on the airflow basic law,this paper demonstrates the problems existing in the indirect adjustment model of resistance measurement of mine ventilation network andits solving process[1]. Applying the fundamentals of least square adjustment[2],the authorsset up a new model of correlated adjustment of condition equations.The solving process ofthe new model is put forward with a practical example.
