| 摘 要： | 鸡西矿区煤炭开采过程中瓦斯涌出量大，煤层渗透率低，严重威胁矿井的正常生产。目前矿区为治理瓦斯，加大煤层气抽采，采用低透气性煤层的高位巷道抽采、高位钻场近水平钻孔、煤层钻场仰角钻孔抽采、顶板大直径水平钻孔等抽采方法，取得了良好的抽采效果。

| Abstract: | The large gas liberation during the coal mining, together with low-permeability coal seams, seriously threatens the mine production in Jixi Coal Mining Area. Currently, in order to control gas and enhance CMM recovery, various methods are adopted in Jixi Coal Mining Area such as upper roadway CMM drainage of lowpermeability coal seams, upper near-horizontal hole drilling, coal seam plus-angle hole drilling, and roof large-diameter horizontal hole drilling, with satisfactory drainage results. |
