摘要
概述了沿煤层定向钻进技术的发展现状及其定向钻进系统特点,基于该技术在宁夏矿区瓦斯抽采中的工程实践,综合分析了沿煤层定向钻孔的瓦斯抽采效果与各抽采参数间的相互关系,通过与该矿传统穿层钻孔瓦斯治理技术相比较,得出了沿煤层定向钻进技术在瓦斯治理工程中的7大优点,为该技术在国内相应地质条件下的推广应用提供了可靠的依据。
The paper introduced the development status of the directional drilling technology along seam and the features of the directional drilling system.Base on the engineering practices of the technology to the gas drainage in Ningxia Mining Area,in comprehensive investigation of the gas drainage results of the directional drilling along seam and the relative relationship between each gas drainage parameter,in comparison with the conventional gas control technology with the borehole drilling in the strata of the ...
