红透山矿业深矿井循环通风实践

Practice of circulating ventilation at deep mine in Hongtoushan Mine

抚顺红透山矿业有限公司铜锌矿针对矿井深度1300 m,风路长以及浅部回风系统排风能力低,通风效果不好的情况,对矿井通风系统进行改造。在采取降低回风段通风阻力,井下集中放炮和空区自净等技术措施的基础上拟定并实施了可控循环通风方案,并取得了良好的通风效果。

Operational depth of mine at Hongtoushang Mine Co. , Ltd. , has reached 1300 m and its ventilation is poor effect due to long ventilation path and low capacity of air exhaust in shallow return air system in the mine, so ventilation system in the mine had a need for improvement. On the basis of taken measures including cutting resistance in return path, concentrated blast for self-cleaning of mined-out area, controlled circulating ventilation process was applied, which has got a good effect.
