摘要
结合三山岛金矿的具体情况,因地制宜地研究应用了以回风侧为主的多级机站通风系统模式。在该矿的通风系统改造中,建立起了完善的回风侧多级机站通风系统,使Ⅱ、Ⅲ级机站的风机运行效率达到了65%以上,全系统的有效风量率达到70%以上,彻底改善了井下通风状况。
In line with the local conditions of Sanshandao Gold Mine, a mode of multi-staged ventilation system mainh on the wind return side was investigated and used. A perfect return-side multi-staged ventilation system was established in the transformation of the mine＇s ventilation system, thus making the operation efficiency of the fans of Ⅱ and Ⅲ stage fan stations over 65% and the rate of efficient wind amount of the whole system over 70% and thouroughly improving the underground ventilation conditions.
