河东金矿井下深部通风系统优化设计

Optimized Design of Deep Underground Ventilation System of Hedang Gold Mine

根据河东金矿采矿水平向下延伸及深部矿体远离中央系统的情况 ,通过增加东西采区回风井、扩大进风井断面、优选系统风机以及计算机通风网络解算 ,提出深部多级机站通风系统优化方案 。

In view of the fact that the mining level in Hedong Gold Mine extends downward and the deep-laying orebody is far from the central ventilation system,an optimized scheme of ventilation system with multistage fan stations is proposed by increasing the air-return shafts,enlarging the inlet shaft section,optimizing the selection of fans and computer calculating the ventilation network.The ventilation effect is predicted.
