摘要
余吾煤业公司S2107工作面为高瓦斯工作面,经预测回采时瓦斯涌出量可达78.37 m3/min,单纯地利用通风或任何一种瓦斯治理方式不能解决瓦斯问题。为此提出了立体抽采模式,将本煤层顺层钻孔、裂隙带抽采、采空区抽采、高抽巷抽采及地面抽采井抽采结合起来,形成全方位立体式的抽采模式,解决了S2107工作面的瓦斯涌出问题。
The working face of S2107 is high gas working face,and the gas emission amount can reach 55 m^3/ min when predicting coal mining,and the gas can not be solved by using ventilation or any gas treatment method. The author puts forward the three- dimensional drainage mode,will the seam along boreholes,slit with drainage,gob drainage,pumping lane and ground pumping wells drainage combined,form a full three- dimensional drainage pattern,solve the S2107 working face gas emission.
