摘　　要：结合三山岛金矿西山矿区南翼通风需求,综合分析了矿井需风量计算的影响因素,经过类比分析,确定了通风排热降温的需风量。在此基础上,采用三维通风网络模拟解算技术、风机机站及风机优选技术、风机变频调速技术对矿区通风系统的主扇机站进行了优化。结果表明:南风井-330 m主扇及配电硐室改造完毕后,南翼通风系统总回风量达到了217.68 m^3/s,相对于原回风量120 m^3/s提高了97.68 m^3/s,西山矿区南翼通风系统得到了极大优化,主斜坡道及深部作业环境得到了明显改善,生产作业效率提高了5%。By considering the ventilation requirements of the south of Xishan mining area of Sanshandao Gold Mine,the influence factors of the underground air volume calculation is analyzed comprehensively,by analogy analysis,the air volume requirements for ventilation,heat rejection and cooling is determined. Based on the above discussion results,the main fan machine station of the ventilation system of the mine is optimized based on 3D ventilation network simulation calculation technique,optimization and selection technique of fan and its machine station and frequency conversion speed controlling technique of fan machine. The results show that after the optimization of the main fan and power distribution chamber in-330 m level of south air shaft,the total air return volume of south air shaft can be reached to217. 68 m^3/s,which is 97. 68 m^3/s more than the original air return volume（ 120 m^3/s）,it is further indicate that ventilation system of the south of Xishan mining area of Sanshandao Gold Mine is optimized effectively,the working environment of main ramp and deep working face are improved,the underground production efficiency is increased by 5%.
