摘　　要：根据《煤矿安全规程》第153条“采掘工作面进风和回风不得经过采空区或冒顶区”的要求,寨崖底煤业有限公司9#煤层3910大采高(4.5 m)综采工作面大直径钻孔替代联络巷采空区瓦斯抽采技术试验成功。现场试验资料表明,大直径钻孔瓦斯抽采为类似高瓦斯矿井安全高效生产提供了强有力的技术保障,有效解决了上隅角瓦斯超限问题。According to Article 153 of Coal Mine Safety Regulations,which stipulates that the intake and return air of the mining face shall not pass through the goaf or roof caving area,the gas extraction technology of 3910 fully mechanized mining face with large mining height(4.5 m)of the 9#coal seam of Zhaiyadi Coal Industry Co.,Ltd.successfully tested by using large-diameter boreholes to replace the gas extraction technology of the connecting roadway goaf.On-site test data shows that gas extraction through large-diameter boreholes provides strong technical support for safe and efficient production in high gas mines,effectively solving the problem of gas exceeding the limit in the upper corner.
