利用地温预热入风流技术 ,设计了金厂沟梁金矿冬季防冻通风系统。系统运行后 ,各提升井内温度均达 + 2℃以上 ,防止了提升井结冰 ,保证了安全生产。本文所介绍的风流预热技术 ,可供从事矿山通风设计及现场管理人员等参考。 Using the technology of ground temperature preheating and wind flow, a winter antifreeze ventilation system of Jinchangguliang gold mine was designed. After the system is operated, the temperature in each hoistway reaches above + 2 ℃, which prevents the hoist from freezing and ensures the safe production. This article describes the wind preheating technology, ventilation and mine design for mine site managers and other reference.
