| Abstract: | We adopt gob-side entry retaining technology in 1404 coal mining face of Ordos Yanjiaqu coal mine, realize＆quot;Y＆quot; type aeration of working face. Those not only solve the accumulation problem of carbon monoxide in the upper corner, and solve the problem of mining continued tension, and improve the recovery rate. |
