摘　　要：针对潘三矿不同地质条件下的采煤工作面顶板覆岩的移动规律,研究完善了顶板走向钻孔抽放瓦斯的技术,并确定了适合潘三煤层围岩特点的顶板走向钻孔抽放参数,取得了很好的瓦斯治理效果。To counter the movement law of overlying roof strata in the working face under different geologic conditions in Panjiaji No.3 Mine, the authors studied and perfected the gas drainage technique by bore-holes along roof strike and determined the gas drainage parameters by bore-holes along roof strike which is suitable for the feature of surrounding rock in Panjiaji No.3 Mine. Good results were obtained in gas prevention and control.
