| 摘 要： | 沿空留巷技术和Y型通风技术是近年来煤矿生产中应用的新技术,然而上述技术还存在成本越来越高,瓦斯治理困难的问题。本文在三汇一矿倾角20°采煤工作面中实施下行式Y型通风及沿空留巷技术,并用矸沙充填。结果表明该技术能明显降低瓦斯浓度,同时,既能保持巷道稳定而不需再次维修,又能明显降低漏风率和采煤工作面粉尘浓度,改善采煤工作面环境,降低成本,提高效率。

| Abstract: | Gob-side entry retaining technology and Y model ventilation technology are newly used in coal mine production in recent years,yet there still exist some problems such as the higher and higher cost and difficulty of gas control.In this paper,Y model ventilation technology and gob-side entry retaining technology as well as waste filling technique are utilized on the coal face with dip angle of the 20° in the NO.1 coal mine in Sanhui.The experimental results show that the integration technology can obviously reduce the gas concentration of coal face and goaf.It also retains the stability of roadways without maintenance over again and sharply reduce the air leakage rate and dust concentration on coal face.It brings about environmental improvement,cost reduction and efficiency improving. |
