近距離高瓦斯煤層群傾斜高抽技術的應用研究

Application research on the technology of incline high-position alley pumping in multi-coal-seam with close quarters and high-content methane

  • 摘要: 分析了沙曲礦14201工作面的瓦斯涌出特點,對傾斜高抽巷治理瓦斯的工藝技術參數進行了優化,觀測了高抽巷治理瓦斯的效果.研究表明,在沙曲礦三軟條件下近距離高瓦斯煤層群實施傾斜高抽技術治理瓦斯效果明顯,能夠抽放出大量的高濃度瓦斯,為工作面的安全生產提供了技術保障.

     

    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 optimized, 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.
