摘要
闽南小煤矿通风系统大部分因采煤系统不完整或者是多个矿串联通风 ,系统漏风严重 ,受自然风压影响明显 ,而造成风流紊乱 ,通风系统缺乏安全性和稳定性 ,给安全生产带来困难。针对这种情况 ,以黄坑矿为示范区 ,通过通风系统阻力测定及网络解算 ,分析了矿井通风系统阻力分布与风量分配存在的主要问题 。
The mining coal system in Minnan small coal mine is most incomplete,and mine ventilation is bad.Wind flow of the system leaks serious and the natural wind pressure has obviously influenced the ventilation system’securitiy and stabilitiy.It makes many safety prodution difficult .This paper takes a study on the ventilation system of Huangken Coal Mine and analyzes some main problems about resistance distribution and wind quantity distribution by measuring the ventilation resistance and calculating the ventilation net,and then points out corresponding solving countermeasures.
