由于受到各种地质条件的影响，在煤矿综采设备的拆除过程中，虽然已经停止回采，各种压力显现已经稳定，但仍会出现瓦斯涌出异常现象，给回撤工作带来安全隐患。结合城郊煤矿2505综采工作面的实际情况，改变常规的回撤工艺，通过留设回撤通道和维护，实现了回撤工作面全风压通风，施工期间瓦斯得到了有效的控制，既保证了施工安全，又实现了矿井生产的正常接替。

Due to the influence of various geological conditions,although has stopped working,all kinds of pres-sure behavior have stabilized,but abnormal gas emission phenomenon still appear in the process of fully mechanized equipment dismantling,will bring safety hidden trouble to retreat work.Combines the actual situation of Chengjiao coal mine 2505 fully mechanized coal mining face,by changing the conventional retreat process and establishing re-treat channel,realized full wind pressure ventilation in retreat working face.During the construction,the content of gas was effectively controlled,ensures construction safety and realizes normal replacement of working face.
