基于气压计基点法测定矿井通风阻力

Measurement of mine ventilation resistance based on base points method with air gauge

为准确、快捷的测定矿井通风阻力,并为改善矿井通风系统、减少通风阻力、降低矿井主通风机的电耗提供依据,本文结合某矿井的测定实例,介绍了气压计基点法在矿井通风阻力测定中的应用,并对矿井2条路线上每段巷道的阻力分布情况进行了分析,结果表明,该矿通风难易程度为容易,大阻力段主要分布在回风联巷、总回风巷和回风立井。讨论了总回风巷阻力大的原因,并提出了合理的建议。

In order to measure the mine ventilation resistance accurately and quickly,and improve the mine ventilation system,reduce the ventilation resistance and the power consumption of the mine main ventilator,the application of the base points method with air gauge in the measurement of the mine ventilation resistance combined with the measurement example was given.The measurement results showed that the mine ventilation was easy.The resistance distribution of each roadway in the two routes of the mine was analyzed.The analysis showed that the large resistance section of the mine was mainly distributed in the return air combined roadway,the total return air roadway and the return air shaft.The reason of high resistance of the total return air roadway was discussed in detail,and some reasonable suggestions were put forward.
