摘要
利用VLD-1000型千米钻机在高突矿井煤层掘进中进行预抽,可以提高高突矿井掘进工作面单轮掘进水平。阐述了千米钻孔在山西晋煤集团沁秀煤业有限公司坪上煤矿井下煤层掘进预抽中的应用情况,论证了“大孔径、长钻孔”预抽工艺的优越性。
The VLD-1000 kilometer drilling rig is used for pre-sumping of this coal seam in the coal seam excavation of high-burst mines,thus improving the single advance level of the excavated working face of high-burst mines.This paper describes the research and analysis of kilometer drilling in the pre-sumping of underground coal seam.
