| 摘 要： | 获各琦铜矿利用地温预热的原理,设计了冬季井筒防冻通风系统。该预热系统经过一年多的运行,采空区及废旧巷道可使约63m^3/s的冷空气由-26℃预热到+2℃以上,有效地降低了冬季期间进风井的预热压力及预热成本,节省了大量能源消耗。在实践上证明了利用采空区及废旧巷道预热冬季入风流在技术上的有效性、经济上的合理性和安全上的可靠性。

| Abstract: | Huogeqi Copper mine used the principle of preheating the ground temperature to design the shaft antifreeze ventilation system in winter.After more than one year of operation,the preheating system can preheat the cold air of about 63 m^3/s from-26℃to over+2℃through the abandoned laneway and goaf,which effectively reduced the preheating pressure and cost of the shaftduring winter,and saved a large amount of energy consumption.And the practiceproved the technical effectiveness,economic rationality and safety reliability of using the goaf and the waste roadway to preheat the winter inflow. |
