贺西煤矿井下Y型通风方式应用研究

Study on the Application of Y-type Ventilation in Underground Shaft of Hexi Coal Mine

贺西煤矿部分采煤工作面回风巷瓦斯超限报警情况多次发生,为了消除瓦斯隐患,本文分析了Y型通风模式在煤矿通风系统中的使用方法和通风优势,并在贺西煤矿采煤工作面进行应用,有效解决了工作面瓦斯超限报警情况,提高了矿井安全生产水平。

The alarm of gas overrun in the air return lane of some coal mining face in Hexi Coal Mine occurred many times. In order to eliminate the hidden danger of gas, this paper analyzes the use method and ventilation advantage of Y type ventilation mode in coal mine ventilation system, and applies it in the coal mining face of Hexi Coal Mine, which effectively solves the overlimit alarm situation of gas in the working face, and improves the safety production level of the mine.
