According to the drilling method, the drilling machine can be divided into four categories: (1) impact drilling machine: wire rope impact, drill pipe impact drilling machine. (2) Rotary drilling rig: vertical shaft type-hand-handle feed type, spiral differential feed type, hydraulic feed type drilling rig; Rotary type-steel rope plus and minus pressure type, hydraulic cylinder plus and minus pressure type drilling rig; Mobile gyrator type-full hydraulic power head type, mechanical power head type drilling rig. (3) Vibration drilling rig. (4) Composite drilling rig: vibration, impact, rotation, static pressure and other functionsDifferent combinations of drilling rigs compounded together.
