【摘要】 分析了沙曲矿14201工作面的瓦斯涌出特点,对倾斜高抽巷治理瓦斯的工艺技术参数进行了优化,观测了高抽巷治理瓦斯的效果．研究表明,在沙曲矿三软条件下近距离高瓦斯煤层群实施倾斜高抽技术治理瓦斯效果明显,能够抽放出大量的高浓度瓦斯,为工作面的安全生产提供了技术保障．更多还原

【Abstract】 The characters of methane emission at the working face No.14201 in Shaqu Coal Mine were analyzed,the technical parameters to control methane by incline high-position alley pumping were opti- mized,and its control efficiency was investigated.The results showed that controlling methane in Shaqu Coal Mine by incline high-position alley pumping was very efficient,a great deal of high-concentration methane had been taken out with the pumping system,and this technique supplied a technical guarantee for safe production in the working face.更多还原
