深部矿井TBM掘进巷道通风及降温耦合模拟分析
Coupling simulation analysis of ventilation and cooling in TBM tunneling roadway of deep mine
摘要
Abstract
Objectives Aiming at the high-temperature problem of deep roadways in tunnel boring machine(TBM)tunneling,Methods the non-isothermal flow coupling theory was constructed based on the k-ε tur-bulence equation and fluid heat transfer equation to simulate the evolution of wind speed and temperature in the roadway.The effects of different air duct outlet wind speeds,different air duct outlet temperatures and different air duct positions on the ventilation and cooling process in the roadway were studied.Results The results showed that the average wind speed in the roadway was essentially linear with the wind speed at the outlet of the air duct,and the ventilation and cooling effect of the air duct positioned at the top of the roadway was the most effective.The wind speed at the outlet of the air duct exhibited a negative expo-nential correlation with the roadway temperature,indicating that as wind speed increased,temperature de-creased.Additionally,the outlet temperature of the air duct was linearly related to the average temperature of the roadway,with roadway temperature rising as the outlet temperature of the air duct increased.The polynomial relationship between the outlet wind speed and the outlet temperature of the air duct was deter-mined for conditions when the tunneling face temperature was 26 ℃ and below.Conclusions The research results provided a reference for addressing the high-temperature issues encountered in TBM tunneling deep roadways.关键词
