Study on Ventilation System of Preventing Frozen Shaft in Winter in Yuerya Gold mine

Abstract

Abstract: Aiming at shaft freezing phenomenon appeared in northern region in the chilly winter，the principle of the temperature preheating is expounded，the technology by temperature preheating wind is put forward，and the ventilation system of preventing shaft freezing with waste roadway and mine goaf is designed in Yuerya Gold Mine.In operation，the temperature in shaft is raised to + 2 ℃ above，which effectively prevent shaft frozen，ensure safe production，and save a lot of energy consumption caused by human.

Key words: Ventilation system, Temperature preheating, Waste roadway, Hoisting shaft
