Abstract

The aerothermodynamic parameters of air are studied in shafts of mines of NorNickel’s Polar Division. The total pressure and temperature measurements, as well as the air density calculations in KS-2, GS and VC-4 shafts in Oktyabrsky Mine show the linear total pressure dependence on the shaft depth and the essentially nonlinear dependence of air temperature and density on the depth of shafts at intersections with ventilation channels and horizons. The lengths of sections of leveling of air parameters behind the intersections are estimated. The authors propose a new method to determine aerodynamic drag coefficients in mine shafts and calculate ADC for 28 mine shafts in the Norilsk Region. The calculation results are used in mathematical modeling of mine ventilation networks and in ventilation designs for new mine sites.

一种确定铜镍矿竖井气动阻力系数的方法

摘要

在 NorNickel 极地部门的矿井中研究空气的空气热力学参数。Oktyabrsky 矿的 KS-2、GS 和 VC-4 竖井的总压力和温度测量值以及空气密度计算表明，总压力与竖井深度呈线性关系，而空气温度和密度基本上呈非线性关系。与通风通道和地平线相交处的竖井深度。估计交叉口后面的空气参数调平段的长度。作者提出了一种确定矿井气动阻力系数的新方法，并计算了诺里尔斯克地区 28 个矿井的 ADC。计算结果用于矿井通风网络的数学建模和新矿区的通风设计。
