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。
Mine ventilation resistance measurement is the main content of coal mine safety management, the size of the resistance directly affects the mine ventilation effect. According to the actual situation of the ventilation system of Xinmin No.2 Mine, the ventilation resistance was measured by using the barometer base point method. The reliability of the determination result was confirmed through the calculation of the measurement data and the error analysis of the calculation results, thus revealing the ventilation of the mine The basic situation of resistance distribution provides the basis for scientific management of mine ventilation system in the future.
