摘　　要：为了采取合理的瓦斯抽采技术,实现矿井安全高效开采,对朱集煤矿13-1煤层实行高位钻孔以及上隅角采空区埋管作为抽采瓦斯实验方案。通过对现场工程实践以及实测数据进行对比分析,得出了实验结果。结果表明:应用高位钻孔瓦斯抽采技术的抽采效果十分明显,且工程施工费用较低,易于生产管理,该抽采技术适用于朱集煤矿采空区瓦斯抽放。In order to take reasonable gas extraction technology and achieve safe and efficient mining, the methods of high position drilling technology and gas drawing of buried-pipe in mined-out area were selected, and an experi- ment scheme was designed in ZhuJi mine 13-1 coal seam. From comparison and analysis of the field practice and the measured data, it showed that high position drilling technology for gas drawing is applicable in mined-out area because of its low cost, obvious effect and easy production management. The extraction technology is suitable for goaf gas drainage in ZhuJi coal mine.
