| 摘 要： | 利用澳大利亚生产的VLD—1000型千米钻机,在突出煤层掘进中打钻预抽瓦斯是近几年发展起来的一项新技术。本文通过对澳大利亚千米钻机在沙曲矿突出煤层掘进预抽中的应用研究及分析,论证了"大孔径、长钻孔、长时间"预抽工艺的优越性。

| Abstract: | It is a new technology developed in recent years using the VLD-1000 drilling rig made in Australia which can drill with the depth of 1 km to drill in an outburst coal seam for pre-pumping gas.Based on the research on the application of the VLD-1000 drilling rig in the outburst coal seams for pre-pumping gas,the conclusion can be made that "large aperture,long drill,enough time"pre-pumping techniques have much advantages in the application. |
