摘要
针对北方地区冬季严寒而出现的入风井冰冻现象,阐述地温预热原理,提出利用地温预热入风流技术,设计了峪耳崖金矿冬季利用废旧巷道及采空区防冻通风系统。系统运行后,各入风井内温度达+2℃以上,有效防止了入风井结冰,保证了安全生产,节省了大量人为能源消耗。
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 sys- tem 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.
