摘　　要：石湖矿业三期工程进入深部开采,深部矿体向南侧伏,造成北风井通风效果不明显,新鲜风量严重不足,污风串联严重,寒冷季节进风井口结冰,严重影响矿山安全生产。针对这一问题,在通风系统测定的基础上,结合矿山生产实际情况,提出两翼进风多井回风隔离式通风系统及地温预热防冻井改造方案,工程应用取得良好效果,验证了方案的可行性。The deep orebody was lateral trending southward at the third phase of Shihu Mining, resulting in insignificant ventilation effect of the north shaft well, serious shortage of fresh airflow, dirty air series connected seriously, freezing the intake shaft in the cold season, and influences the safe production in the mine seriously. For this problem, based on the determination of ventilation system, the modification scheme was put forwards that two wings intake and multi-well returning air isolated ventilation system and geothermal preheating antifreeze wells program, with the actual production. The project has achieved good results and verified the feasibility of the scheme.
