Abstract: According to the technical problems existed in the available mine directional drilling technology and equipment,a ZDY 12000 LD high power directional drillin g rigdrilling mud pulse wireless measurement system while drilling,assorted drilling tools and compound directional drilling technique were provided to the mine directional drilling.In combination with the site test,a directional long distance drilling of the main borehole with the depth of 1 881 m was completed. The high power,strong drilling and strong accident handling capacity of the ZDY 12000 LD drilling rig were verified.Meanwhile,the measuring accuracy of the wireless measurement while drilling was high,ass orted compound directional drilling technology could make a smooth borehole wall,less cuttings,less borehole curvature and high drilling efficiency.The above drilling techn ology and equipment could meet the construction requirements of the horizontal directional long distance deep borehole and others.
