湖南某矿山通风系统优化研究

Optimization of Ventilation System of a Mine in Hunan

针对湖南省内某矿山24线采区通风系统存在主平硐风量､风向不稳定,污风循环及部分作业区域未有规划而导致的采区通风不良的问题,研究根据矿山实际情况采用增加主平硐进风辅扇辅助进风,同时规划作业通风盲区回风线路并增加相应的通风辅扇,从而实现了采区通风进､回风线路明确,解决了该采区通风系统技术问题,符合矿山生产通风需求。

In view of the problems of poor ventilation in the mining area caused by unstable air volume and wind direction of the main adit,sewage air circulation and no planning in some operation areas in the ventilation system of line 24 mining area of a mine in Hunan Province,it is studied to increase the auxiliary air inlet of the main adit according to the actual situation of the mine,plan the return air line in the blind area of operation ventilation and increase the corresponding auxiliary ventilation fan.Thus,the ventilation inlet and return air lines in the mining area are clear,the technical problems of the ventilation system in the mining area are solved,and it meets the ventilation requirements of mine production.
