矿井外部漏风率精准测算方法的研究与应用

Research and Application of Accurate Measurement Method of Mine External Air Leakage Rate

本文以陈四楼矿为例,根据通风系统、主要通风机及附属设施的实际布置位置,结合井筒深度、温度对风量的影响,选定该矿矿井外部漏风率基本参数的测定方法为风表直接测定法,采用了热力学方程的计算方法,最终测算出陈四楼矿外部漏风率北风井为1.25%,南风井为1.12%。

This article takes Chensilou Mine as an example,and according to the ventilation system,the main ventilator and ancillary facilities of actual location,combined with the depth of the shaft,the influence of the temperature of air volume,the paper selected the mine pit external leakage rate method for determination of the basic parameters for wind table direct measurement method,used the thermodynamic equation and the calculation method to ultimately measure it that Chensilou ore external leakage rate of the north wind wells is 1.25%,the south wind wells 1.12%.
