摘要
铜绿山铜铁矿根据其开拓系统 ,将两台主扇安装在井下两翼回风道 ,形成了上下盘多井中央进风 ,两翼对角抽、压风的通风系统 ;阶段通风网络采用两翼平行双巷双上下行通风。这种通风方式强化了系统的排烟、排尘效果 ,使各中段和采场自然分风比较均匀 ,各中段污风串联得到有效控制 。
In Tonglushan Copper-Iron Mine, according to the case of the mine development system, the two main fans are installed in the underground return airways at two ends of ore deposit,thus forming a ventilation system which takes multi shafts located in the middle of both hanging and bottom walls of ore deposit as the air inlet shafts,and exhausts contaminated air and presses air to the outlet air shafts diagonally at the two ends of ore deposits.For level ventilation network,parallel doubles drifts and upwards and downwards ventilation pattern at two sides of ore deposit have be applied. The ventilation system, which has enforced exhausting and dust removal, offers good distribution of air flow to all levels and stopes, effectively controls the series accumulation of polluted air in various levels, thus reduces structures for air control.
