摘要
城郊煤矿为瓦斯矿井,但2505综采工作面回撤期间瓦斯异常涌出,严重影响了工作面回撤进度。为了解决回撤期间瓦斯超限问题,采用全风压通风与局部通风相结合的方法治理瓦斯,取得了良好效果,达到了安全、高效回撤的目的。
The Chengjiao mine is a lower gassy mine,but there appear abnormal gas emission in 2505 fully mechanized coal face during the retreat,this seriously affected the working face retracement progress.In order to solve the gas overrun problem during the retreat,adopts full wind pressure ventilation combined with local ventilation method for gas,this method has obtained the good effect and achieve the purpose of the safe and efficient retracement.
