摘　　要：余吾煤业属高瓦斯矿井,采用综采放顶煤技术,其煤层透气性低、瓦斯含量大,尤其是采空区瓦斯涌出量较大,一直影响工作面的正常生产,针对这一问题,利用千米钻机向煤层顶板打钻抽采瓦斯,通过优化钻孔的布置,取得了良好的抽采效果,确保了综放工作面的安全生产,提高了工作效率。Yuwu coal mine, as a high gas mine, applied fully mechanized caving technology. With poor coal seam permeability, the gas content was high, the goaf gas emission was especially serious, affecting the regular production of the mining face. To solve this problem, kilometer rig was utilized to drill gas drainage boreholes in the roof. Through the optimization of boreholes arrangement, favorable drainage effect had been obtained, ensuring the safety production in the fully - mechanized caving face, and the working efficiency was improved.
