三交河煤矿综采工作面“U”型通风系统瓦斯治理技术

Gas Control Technology of “U” Shaped Ventilation System in Fully Mechanized Coal Face of Sanjiaohe Coal Mine

根据三交河矿"U"型通风系统2-504瓦斯涌出情况及规律,研究运用的"三管齐下"全方位瓦斯治理技术,能够有效地降低工作面及上隅角的瓦斯,确保采煤工作面的安全生产,促进煤矿开采技术的发展。

Through the gas emission situation and law of ＂U＂ shaped ventilation system 2-504 in Sanjiaohe Coal Mine,it studied the application of the ＂three-pronged＂ omnibearing gas control technology,which could effectively reduce the gas of the working face and the upper corner.It ensured the safe production of the coalface,promoted the development of the coal mining technology.
