吉尔吉斯斯坦左岸金矿深部通风系统优化设计及改造实践

Designand practice of deep ventilation system optimization in Zuo-an Gold Mine in Kirghizia

随着矿山深部开拓工程的实施及年产量的增大,矿井通风常会滞后于生产,造成矿井风流紊乱、主要工作面风量不足,因此,必须适时的对通风系统进行调整和改造。本文简述了左岸金矿井下深部通风系统现状,根据通风系统的测定结果,对该通风系统存在的问题进行了分析与评价,并提出了通风系统的整改技术措施和深部优化改造方案,在实践中取得良好的效果,可供类似矿山参考。

With the implementation of deep exploitation projects and the increase of annual output,ventilation of mines often lags behind production,resulting in air disorder in the mines,insufficient wind in the major working face,etc.Therefore,the ventilation system must be adjusted and modified timely.This paper sketches the current situation about deep department in the pit of Zuo-an gold mine＇s ventilating system,according to the result of determining ventilating system,problems existing in the ventilation system are analyzed and evaluated,at the same time,it puts forward rectification technology and deep department optimization design proposing in the ventilating system,as a result,good ventilation effect is obtained,which can offer reference to similar mines.
