摘　　要：为解决铜绿山铜铁矿通风系统存在的矿井风量分配不合理、井下污风循环、局部区域通风效果差、井下通风构筑物管理困难等问题,根据矿山实际生产情况,重新计算了矿井总风量,并提出3种优化改造方案。经过技术经济对比,选择了多级机站通风系统为最优方案。经三维通风软件模拟解算,矿井总风量达到428.03 m^3/s,满足计算的矿井总风量。采用多级机站通风方式,且各区域分区通风,更容易实现风量合理分配,避免各通风区域之间的干扰,提高通风系统稳定性,有效增加通风系统深部进风。The ventilation system of Tonglushan Copper and Iron Mine has problems such as unreasonable air volume distribution,underground sewage air circulation,poor local ventilation and difficult management of underground ventilation structures.In order to solve these problems,combined with the actual production situation to recalculate the total air volume of the mine,three optimization schemes are proposed.After technical and economic comparison and analysis,the multi-level station ventilation system is determined to be the optimal solution.Through the simulation and calculation of the three-dimensional ventilation software,the total air volume of the mine reaches 428.03 m^3/s,which meets the calculated total air volume of the mine.The ventilation mode of the multi-level machine station realizes the regional ventilation of each area,and the air volume distribution is more reasonable,avoiding the interference between the ventilation areas,improving the stability of the ventilation system,and effectively increasing the deep air intake of the ventilation system.
