新民二矿通风阻力测定及分析

Measurement and Analysis of Ventilation Resistance in Xinmin 2ed Coal Mine

矿井通风阻力测定是煤矿安全管理的主要内容,阻力大小直接影响矿井的通风效果。根据新民二矿通风系统实际情况,运用气压计基点法对其通风阻力进行了测定,通过对测定数据的计算以及对计算结果的误差分析,确定了测定结果的可靠性,从而揭示了该矿通风阻力分布的基本情况,为今后矿井通风系统科学管理提供了依据。

The measurement of ventilation resistance is an important task in coal mine safety management,the magnitude of ventilation resistance affects the ventilation system＇s efficacy directly.This paper according to the current status of ventilation system of Xinmin 2ed Coal Mine,a basic point method with barometer is applied to determine the ventilation resistances of the coal mine,through the measurement data calculating and the calculating results error analysis,determines the reliability of the measurement results,and the ventilation resistance distribution is analyzed with the measurement data,which could be used in the scientific management in the future coal mine ventilation system.
