摘要 为开采低透气性高瓦斯突出的C13主采煤层,需先开采上覆的C15解放层,深部高瓦斯、低透气性煤与瓦斯突出煤层群开采,要求改变工作面传统的"U"型通风方式为无煤柱沿空留巷"Y"型通风方式。进行了深井开采沿空留巷巷内支护设计、巷旁支护设计及留巷期间巷内加固设计,通过工业试验表明,沿空留巷技术在谢一矿512(5)工作面取得了较好效果。 In order to explore C13 coal seam with low permeability and high - gas outburst,firstly,mine overlying C15 liberated seam and deep coal seams of coal - and - gas outburst with low permeability and high gas;Secondly,the traditional U - type ventilation mode of working face is changed into Y - type ventilation mode of gob - side entry retaining. The paper carried on entry - in support design of gob - side entry retaining about deep mining,roadside support design and entry - in reinforcing design during the period of gob - side entry retaining.Through industrial tests,the technology of gob - side entry retaining gained better results in the 512(5) working face of Xieyi Mine.
