Abstract: The flexible two-position directional drilling rig ZDY6000LD(F) was developed using the concept of drilling and directional power integrated into the pump truck, after analyzing narrow coal mine roadway in southwest directional drilling requirements, through the development of double motors remotely adjusting the series-parallel hole power head, large angle of multistage cylinder overpressure protection tuning angle device, serial combination cylinder type feeding device, new alloy steel wear-resisting guide rail and closed combined filtration hydraulic system, we implement the drilling rig structure optimization and performance improvement, and improve the working life of the key components, enhance the hydraulic system cleanliness and safety, improve the technology of drilling adaptability. And drilling construction has carried on the roof high level directional borehole in complex formation of Qinglong Mine in Guizhou Province. Experimental results show that drilling rig has a strong adaptability, high drilling efficiency, high precision borehole trajectory control and strong operability and construction.
