1.The brief introductions of KY-200 metal mine exploration drilling rig KY-200 full hydraulic tunnel drilling rig is widely used for tunnel and surface geological exploration and can drill the hole from any angle. The KY-200 full hydraulic drilling rig adopts the structure of all hydraulic power head and consists of three parts: main engine, pump station and operation floor. The rig is easy to disassemble and is convenient to transport. The drilling rig arrangement is flexible. Drilling pipe screwing and unscrewing is mechanized. It can save labour cost and improve work efficiency. And it has infiniTely variable speeds. KY-200 full hydraulic drilling rig has the function of linkage. It is simple and safe through controlling the operation floor. The spindle of the gyration adopts the through hole structure. The length of the drill rod is not restricted by the drilling machine, and it can also be applied to the diamond wire-line coring drilling.
