摘要
鄂尔多斯闫家渠煤矿1404采煤工作面上风巷采用沿空留巷技术,实现了工作面"Y"型通风,既解决了上隅角一氧化碳积聚问题,又解决了采掘接续紧张问题,同时提高了采区回采率。
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.
