采煤工作面“Y”型布置方式通风技术研究

Study on ventilation technology of mining working face Y type layout

采用通风方式治理瓦斯和防灭火问题的途径有两种,一是利用串并联风路特性,二是利用角联风路特性。采煤工作面"Y"型布置表明其通风系统有三条通风巷道组成,瓦斯治理或防灭火治理效果则由三条通风巷道的风向和风量共同决定。

There are two methods to control gas by ventilation and fire prevention, one is using the features of series parallel connection, another is diagonal branches. There are three ventilation roadways in mining working face Y type, the effect of gas and fire control and prevention depends on the wind orientation and volume of the three ventilation roadways.
