| 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 m3/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. |
