为了解决南阳煤业3208工作面瓦斯治理问题,通过对3#煤层瓦斯含量参数测定及数据计算,预测3208工作面瓦斯涌出量,分析瓦斯涌出构成来源,利用“U并U”的通风方式,在3208工作面第二回风巷敷设抽采系统支管,进行采空区内埋管抽采瓦斯,利用地面瓦斯抽采系统,达到有效治理工作面瓦斯的目的,保证了3208工作面的安全生产。
In order to solve the problem of gas control in 3208 working face of Nanyang Coal Mine, the gas emission of 3208 working face is predicted through the measurement and data calculation of the gas content of No.3 coal seam. The gas emission constituent source is analyzed and the “UUU” Ventilation mode, the second return airway 3208 working face laying drainage system branch pipe, gob tube buried gas drainage, the use of surface gas drainage system to achieve effective control of the face gas, to ensure that the 3208 face The safety of production.
