Hdd 70x6.5mm 3m Long Drill Pipe Casing ISO Passed
MECA Insert Drill Rod 70*11mm 3m Long for coal mine-Modular Electrically Connected Cable Assembly
Directional drill rod is mainly used for directional horizontal drilling in coal mine tunnel. It coordinates with ground display device to display drilling trajectory data in real time. The operator can adjust the direction of drilling trajectory according to the display data in time, so as to achieve the goal of directional drilling. It is widely used in directional drilling control in geological, mining, coal, petroleum, water and other industries.
Applications:
Directional long boreholes drilling and water exploration and drainage boreholes drilling in underground coal mines.It can also be used for the drilling of nearly horizontal directional boreholes in surface or tunnel.
