摘　　要：在分析煤矿瓦斯抽采理论、抽采技术等基础上,对地面钻井抽采瓦斯技术进行优化,并提出合理布置钻孔、“一井三用”等改进措施。通过在某煤矿工作面上的瓦斯抽放实践,上隅角瓦斯超限问题得到良好解决,证明该技术抽采采空区瓦斯的效果显著。On the basis of analyzing the theory and technology of coal mine gas extraction,the optimization of surface drilling gas extraction technology is conducted,and improvement measures such as reasonable arrangement of boreholes and"one well,three uses"are proposed.Through the practice of gas drainage in a coal mine working face,the problem of gas exceeding the limit in the upper corner has been well solved,and it has been proved that the technology has significant effect on gas drainage in the goaf.
